Teaching Material on

“Enzymes” for MBBS First

Professional Students, 2014 Batch

ENZYMES

Biologic polymers that catalyze chemical reactions that

make life possible.

BIOMEDICAL IMPORTANCE

Presence & maintenance of a complete & balanced set of

enzymes is essential for the breakdown of nutrients to

supply energy & chemical building blocks. These building

blocks assemble into proteins, DNA, membranes, cells &

tissues. Energy harnessed is used to power cell motility,

neural functions & muscle contraction.

The ability to assay the activity of specific enzymes in

blood, other tissue fluids or cell extracts aids in diagnosis

& prognosis of disease.

Enzymes can be employed in the clinical laboratory as

tools for determining critical metabolites e.g. glucose

oxidase is frequently utilized to measure plasma glucose

concentration.

Enzymes are also employed as tools for treatment of

injury & disease. Tissue plasminogen activator, or

streptokinase is used in the treatment of MI while trypsin

has been used in the treatment of cystic fibrosis.

Sensitivity of enzyme assays can be exploited to detect

proteins that lack catalytic activity in ELISA.

A complete balanced set of enzyme activities is of

importance for maintenance of homeostasis.

They are targets of choice for drugs that cure or

ameliorates human disease. Defective enzymes/ deficiency

in the quantity or catalytic activity of key enzyme can

Page 31: CURRICULUM VITAE Shagufta Moin, M.D. · comparative study 8. Dr. Puneet 2012 Comparative study of plasma ascorbic acid Parasurampuria and serum nitric oxide levels in senile cataract

result from genetic defects/ genetic mutations, nutritional

deficits or toxins/ infections by viral or bacterial

pathogens (e.g. vibrio cholerae)

INDUSTRIAL USES

Proteases & amylases augment the capacity of detergents

to remove dirt & stains.

Enzymes also play a role in producing or enhancing the

nutrient value of food products for both humans &

animals. The protease renin, for e.g. is utilized in the

production of cheese, while lactose is employed to remove

lactose from milk for the benefit of lactose-intolerant

persons deficient in this hydrolytic enzymes.

PROPERTIES OF ENZYMES

Enzymes catalyze conversion of one or more compounds

(substrates) into one or more different compounds

(products). They possess two important properties-

EFFICIENCY- enhance the rate of corresponding non-

catalyzed reaction by factors of atleast 106

SPECIFICITY- they are specific both for the type of

reaction catalyzed & for a single substrate or a small set of

closely related substrate. Enzymes are also stereo-specific

catalyst & catalyze reactions of only one stereo-isomer of

a given compound. For e.g. D- but not L- sugars, L- but

not D- amino acids.

Most of the enzymes are proteins, exceptions include

ribosomal RNAs, & self-cleaving or self-splicing RNA

molecules known collectively as ribozymes.

CO-FACTORS, CO-ENZYMES, PROSTHETIC

GROUPS

Many enzymes contain small non-protein molecules &

metal ions that participate directly in substrate binding &

catalysis. They are termed as prosthetic groups/ co-factors/

co-enzymes. Co-factors bind in transient dissociable

manner either to the enzymes or to the substrate. Most

Page 32: CURRICULUM VITAE Shagufta Moin, M.D. · comparative study 8. Dr. Puneet 2012 Comparative study of plasma ascorbic acid Parasurampuria and serum nitric oxide levels in senile cataract

common co-factors are metal ions. Enzymes that require a

metal ion as co-factor are termed metal activated enzymes.

Prosthetic groups are tightly & stably integrated into a

protein‘s structure by covalent & non covalent forces.

Metals are the main prosthetic groups. Enzymes that

contain tightly bound metal ions or metal ion as prosthetic

group are termed metallo enzymes.

Co-enzymes serve as recyclable shuttles or group transfer

agents that transport many substance from one point

within the substrate from others. B complex group of

vitamins supply important components of numerous co-

enzymes.

ENZYME CLASSIFICATION

1. Oxidoreductasescatalyze oxidations and

reductions, e.g. lactate dehydrogenase

2. Transferases catalyze transfer of groups such as

methyl or glycosyl groups from a donor molecule to an

acceptor molecule, e.g. hexokinase.

3. Hydrolases catalyze the hydrolytic cleavage of C-C,

C-O, C-N, P-O, and certain other bonds, including acid

anhydride bonds, e.g. acetylcholine esterase.

4. Lyases catalyze cleavage of C-C, C-O, C-N, and

other bonds by elimination, leaving double bonds, and

also add groups to double bonds, e.g. aldolase.

5. Isomerases catalyze geometric or structural changes

within a single molecule, e.g. phospho-triose

isomerase.

6. Ligases catalyze the joining together of two

molecules, coupled to the hydrolysis of a

pyrophosphorylgroup in ATP or a similar nucleoside

triphosphate, e.g. acetyl co A carboxylase.

The IUB name of ―hexokinase‖ is ―ATP:D-hexose-6-

phosphotransferaseE.C. 2.7.1.1.‖ This identifies

hexokinase as amember of class 2 (transferases), subclass

7 (transfer of aphosphoryl group), sub-subclass 1 (alcohol

Page 33: CURRICULUM VITAE Shagufta Moin, M.D. · comparative study 8. Dr. Puneet 2012 Comparative study of plasma ascorbic acid Parasurampuria and serum nitric oxide levels in senile cataract

is the phosphorylacceptor). Finally, the term ―hexose-6‖

indicatesthat the alcohol phosphorylated is that of carbon

six ofa hexose.

ACTIVE SITE

Recognition site for binding of substrates. Within active

site, substrates are brought into close proximity to one

another in optimal alignment with the co-factors,

prosthetic groups & amino acids side chains responsible

for catalyzing their chemical transformation into products.

Catalysis is further enhanced by the capacity of active site

to shield substrate from water, & generate an environment

whose polarity, hydrophobicity, acidity or alkalinity can

differ markedly from that of the surrounding cytoplasm.

MODELS FOR ENZYME CATALYSIS

Emil Fischer proposed that specificity with which

enzymes discriminate their substrates when forming an

enzyme substrate complex was analogous to the manner in

which a mechanical lock distinguishes the proper key. The

lock is formed by a cleft or pocket on the protein‘s surface

that forms part of a region called active site.

Lock and key model of enzyme- substrate binding

This model accounted for the exquisite specificity of

enzyme substrate interactions. The implied rigidity of

enzyme‘s active site failed to account for the dynamic

Page 34: CURRICULUM VITAE Shagufta Moin, M.D. · comparative study 8. Dr. Puneet 2012 Comparative study of plasma ascorbic acid Parasurampuria and serum nitric oxide levels in senile cataract

changes that accompany catalysis. This drawback was

addressed by Daniel Khosland‘s induced fit model which

states that when substrate approach & bind to an enzyme,

they induce a conformational change analogous to placing

a hand (substrate) into a glove (enzyme). The enzyme in

turn induces reciprocal changes in its substrates,

harnessing the energy of binding to facilitate the

transformation of substrate into products.

Induced-fit model of enzyme-substrate binding

MECHANISM TO FACILITATE CATALYSIS

Enzymes use various combinations of four general

mechanisms to achieve catalytic enhancement of the rates

of the chemical reaction

Catalysis by proximity

Acid-base catalysis

Catalysis by strain

Covalent catalysis

Enzymes of aspartic protease family (pepsin, lysosomal

cathepsin, HIV protease) illustrate acid-base catalysis.

Serine protease (chymotrypsin) illustrates covalent

catalysis.

Enzymes catalyzing lytic reactions bind their substrates in

a conformation that is unfavorable for the bond that will

Page 35: CURRICULUM VITAE Shagufta Moin, M.D. · comparative study 8. Dr. Puneet 2012 Comparative study of plasma ascorbic acid Parasurampuria and serum nitric oxide levels in senile cataract

undergo cleavage. This conformation mimics that of the

transition state intermediate, a transient specie that

represents the transition state or a half-way point, in the

transformation of substrate into products. In this state

neither free substrate nor product exits. Energy needed to

reach transition state is known as activation energy.

Stabilization of transition state is a general mechanism by

which enzymes accelerate the rates of chemical reactions.

Transition state analogs are more effective enzyme

inhibitors.

ENZYME KINETICS

It is the field of biochemistry concerned with the

quantitative measurement of the rates of enzyme catalyzed

reactions & the systematic study of factors that affect

these rates.

KINETICS OF ENZYME CATALYSIS

Enzymes accelerate the reaction rates by lowering

activation energy needed for the formation of transition

state. The environment of the active site lower activation

energy by stabilizing the transition state intermediate.

Enzymes bind to TSI more tightly than it does to either

substrates or products.

FACTORS AFFECTING THE RATES OF ENZYME

CATALYZED REACTIONS

Page 36: CURRICULUM VITAE Shagufta Moin, M.D. · comparative study 8. Dr. Puneet 2012 Comparative study of plasma ascorbic acid Parasurampuria and serum nitric oxide levels in senile cataract

Multiple factors affect the rate of enzyme catalyzed

reactions.

Temperature- raising the temperature increases the rates

of both un-catalyzed & enzyme catalyzed reactions by

increasing the kinetic energy & the collision frequency of

reacting molecules. Heat energy can also increase the

kinetic energy of the enzyme to a point that exceeds the

energy barrier for disrupting the non-covalent interactions

that maintains its 3-D structure. The polypeptide chain

then begins to unfold or denature with an accompanying

loss of catalytic activity. Enzymes from humans generally

exhibit stability at temperatures upto 45-55C.

Hydrogen ion concentration- most intracellular enzymes

exhibit optimal activity at pH values between 5 & 9.

Relationship of activity to hydrogen ion concentration is

due to enzyme denaturation at high or low pH & effects

on the charged state of the enzymes, substrates, or both.

Substrate concentration- for a typical enzyme, as

substrate concentration is increased Vi increases (due to

more formation of ES complex) until it reaches a

maximum value Vmax. Further increase in substrate

concentration do not further increase Vi (enzyme is

saturated with the substrate). Shape of the curve that

relates substrate concentration to activity is hyperbolic. At

Page 37: CURRICULUM VITAE Shagufta Moin, M.D. · comparative study 8. Dr. Puneet 2012 Comparative study of plasma ascorbic acid Parasurampuria and serum nitric oxide levels in senile cataract

any given instant only substrate molecules that are

combined with the enzyme as an ES complex can be

transformed into a product.

MICHAELIS-MENTEN EQUATION

Michaelis-Menten equation illustrates relationship

between initial reaction velocity Vi& substrate

concentration [S].

Vi = Vmax[S]/KM + [S]

Michaelis-Menten constant (KM), is the substrate

concentration at which the initial velocity is half of the

maximal velocity attainable at a particular concentration

of the enzyme.

LINEAR FORM OF MICHAELIS-MENTEN

EQUATION

The direct measurement of the KM&Vmax often requires

high concentration of substrates to achieve saturating

conditions. A linear form of theMichaelis-Menten

equation circumvents this difficulty & permits Vmax& KM

to be extrapolated from initial velocity data obtained at

less than saturating concentrations of the substrate.

A plot of 1/Vi as a function of 1/ [S], gives a straight line

whose Y intercept is 1/ Vmax& whose slope is KM/ Vmax.

Such a plot is called double reciprocal plot or Line

Page 38: CURRICULUM VITAE Shagufta Moin, M.D. · comparative study 8. Dr. Puneet 2012 Comparative study of plasma ascorbic acid Parasurampuria and serum nitric oxide levels in senile cataract

Weaver Burk plot. X-intercept is -1/ KM , KM is thus

readily calculated from negative x-intercept.

This plot can also be used to determine the kinetic

mechanisms of enzyme inhibitors.

SPECIFIC ACTIVITY, TURN OVER NUMBER,

CATALYTIC CONSTANT

To compare the relative activity of different enzymes or of

different preparations of the same enzyme, several

parameters may be used.

The activity of impure enzyme preparations is expressed

as specific activity (Vmax/ protein concentration).

For a homogeneous enzyme, one may calculate its turn

over number (Vmax/ moles of enzyme present).

If the number of active sites present is known, the

catalytic activity of a homogeneous enzyme is expressed

as its catalytic constantKcat (Vmax/ number of active sites).

Catalytic efficiency of the enzyme is the ratio of two

kinetic constants, Kcat / KM.

ENZYME INHIBITION

Page 39: CURRICULUM VITAE Shagufta Moin, M.D. · comparative study 8. Dr. Puneet 2012 Comparative study of plasma ascorbic acid Parasurampuria and serum nitric oxide levels in senile cataract

Inhibitors of catalytic activities of enzymes can be used

as-

pharmacologic agents

research tools for the study of mechanism of

enzyme action

The strength of interaction between an inhibitor & an

enzyme depends on forces important in protein structure

& ligand binding (hydrogen bonds, electrostatic

interactions, hydrophobic interactions & Van der Waal

forces)

Inhibitors can be classified on the basis of their

site of action on the enzyme

on whether they chemically modify the enzyme

on the kinetic parameter, they influence

Compounds that mimics the transition state of an enzyme-

catalyzed reaction (transition state analogs) or that takes

advantage of the catalytic machinery of an enzyme

(mechanism-based inhibitors) can be potent inhibitors.

Kinetically, we distinguish two classes of inhibitors based

upon whether raising substrate concentration does or does

not overcome the inhibition. Double reciprocal plot

facilitates the evaluation of inhibitors.

COMPETETIVE INHIBITION

Competitive inhibitors resemble substrate (substrate

analog). They bind to the substrate-binding portion of

active site thereby, blocking access by the substrate. Their

effect can be overcome by raising the concentration of

substrate.

Page 40: CURRICULUM VITAE Shagufta Moin, M.D. · comparative study 8. Dr. Puneet 2012 Comparative study of plasma ascorbic acid Parasurampuria and serum nitric oxide levels in senile cataract

Inhibition of the enzyme succinate dehydrogenase by

malonate illustrates competitive inhibition by substrate

analog.Competitive inhibitors act by decreasing the

number of free enzyme molecules available to bind

substrate, i.e. to form ES complex & thus eventually to

form product. A competitive inhibitor has no effect on

Vmax but raises the apparent KM for the substrate.

NON-COMPETETIVE INHIBITION

Anon-competitive inhibitor bear no or little structural

resemblance to the substrate & bind with enzyme at sites

distinct from the substrate binding site. Binding of

inhibitor does not affect the binding of substrate. So,

formation of both EI & EIS complexes is possible. While

E-I complex can still bind the substrate its efficiency at

Page 41: CURRICULUM VITAE Shagufta Moin, M.D. · comparative study 8. Dr. Puneet 2012 Comparative study of plasma ascorbic acid Parasurampuria and serum nitric oxide levels in senile cataract

transforming substrate to product is decreased or generates

product at a negligible rates. Their effects can never be

completely overcome by increase in substrate

concentration. Simple non-competitive inhibitors lower

Vmax but do not affect KM.

IRREVESIBLE INHIBITORS (POISON ENZYMES)

In reversible inhibition the inhibitors form a dissociable

dynamic complex with the enzyme. Fully active enzyme

can be recovered simply by removing the inhibitor from

the surrounding medium. Irreversible inhibitors act

irreversibly by chemically modifying the enzyme. These

modifications generally involve making or breaking

covalent bond with amino acyl residues essential for

substrate binding, catalysis or maintenance of enzyme‘s

functional conformation. These covalent changes are

relatively stable. So, enzyme remains inhibited even after

the removal of the remaining inhibitor from the

surrounding medium e.g. heavy metal atoms, acylating

reagents.

MECHANISM-BASED INHIBITION OR “SUCIDE

INHIBITORS”

Page 42: CURRICULUM VITAE Shagufta Moin, M.D. · comparative study 8. Dr. Puneet 2012 Comparative study of plasma ascorbic acid Parasurampuria and serum nitric oxide levels in senile cataract

Substrate analogs that contain a chemical group that can

be transformed by the catalytic machinery of the target

enzyme. After binding to the active site, catalysis by the

enzyme generates a highly reactive group that forms a

covalent bond & blocks the function of a catalytically

essential residue. They are promising leads for

development of enzyme specific drugs.

FEEDBACK REGULATION

Dietary cholesterol decreases hepatic synthesis of

cholesterol by controlling the expression of the gene that

encodes HMG-Co A reductase (enzyme repression).

FEEDBACK INHIBITION

Feedback inhibition is a process by which the end product

of a multi-step biosynthetic pathway binds to & inhibits an

enzyme catalyzing one of the early step in that pathway.

Feedback inhibitors bear little or no structural similarity to

the substrate of the enzyme they inhibit. They bind at an

allosteric site, spatially distinct from the catalytic site of

the target enzyme. A feedback inhibitors act as negative

allosteric inhibitor & inhibits the first committed step in a

particular biosynthetic sequence. Statins curtail synthesis

of cholesterol by inhibiting HMG-Co A reductase, which

catalyzes a rate limiting state of cholesterol biosynthesis.

In biosynthetic pathways where there are two or more end

products, each end product may only partially inhibit

catalytic activity. The effect of an excess of two or more

end products may be additive or greater than their

individual effect (known as co-operative feedback

inhibition).

PROENZYMES

Proteins that are synthesized & secreted as an inactive

precursor proteins are known as proproteins. Selective or

partial proteolysis converts proprotein to mature protein.

Proproteins forms of enzymes are termed proenzymes or

zymogens. The synthesis & secretion of protease as

proenzyme is to protect the tissue of origin from auto

digestion. E.g. of proproteins include pro-insulin,

Page 43: CURRICULUM VITAE Shagufta Moin, M.D. · comparative study 8. Dr. Puneet 2012 Comparative study of plasma ascorbic acid Parasurampuria and serum nitric oxide levels in senile cataract

pepsinogen, trypsinogen, chymotrypsinogen, several

factors of blood clotting & blood clot dissolution cascade,

& procollagen.

REGULATION OF ENZYME ACTIVITY

Catalytic capacity of the rate-limiting reaction in a

metabolic pathway is the product of concentration of the

enzyme molecules & their intrinsic catalytic efficiency.

Catalytic capacity can be influenced by changing the

quantity of enzyme present & by altering its catalytic

efficiency.

Regulation of enzyme quantity- body proteins are in a

state of dynamic equilibrium, in which they are

continuously synthesized & degraded (turnover). The

absolute quantity of an enzyme is the net balance between

its rate of synthesis & rate of degradation.

Control of enzyme synthesis can be achieved by induction

or repression. Induction of protein synthesis requires hours

to produce significant changes in overall enzyme level.

The ubiquitin-proteasome pathway is responsible both for

the regulated degradation of selected cellular proteins &

for the removal of defective, aberrant proteins. Changes in

protein level generally dominate when meeting long-term

adaptive requirement.

Changes in intrinsic catalytic efficiency can be achieved

by allosteric regulation (binding of dissociable ligands) or

by covalent modification. This can happen within seconds

& best suited for rapid & transient alteration in metabolite

flux.

ALLOSTERIC ENZYMES

Catalysis at the active site may be modulated by the

presence of effectors at an allosteric site. Allosteric sites

are physically distinct from the catalytic sites. They are

multimeric, bind to their substrate at multiple sites (co-

operative binding). Binding of allosteric regulator induces

a conformational change in the enzyme that encompasses

the active site. Shape of the curve that relates changes in

Page 44: CURRICULUM VITAE Shagufta Moin, M.D. · comparative study 8. Dr. Puneet 2012 Comparative study of plasma ascorbic acid Parasurampuria and serum nitric oxide levels in senile cataract

Vi to changes in substrate concentration is sigmoidal,

which is represented by Hill equation.

Two classes of allosterically regulated enzymes are K-

series&V-series. For K-series, the substrate saturation

kinetics is competitive, i.e. KM is raised without an effect

on Vmax. For V-series, the allosteric inhibitors lowers Vmax

without affecting the KM. Alteration in KM or Vmaxare due

to conformational changes at the catalytic site induced by

binding of the allosteric effector at its site. For K-series,

this conformational change may weaken the bonds

between substrate & substrate-binding residues. For V-

series this may be due to alteration in the orientation or

charge of catalytic residues.

ISOZYMES

They are physically distinct versions of a given enzymes,

each of which catalysis the same reaction. Isozymes arise

through gene duplication. They may exhibit differences in

properties such as sensitivity to particular regulatory

factor or substrate affinity that adapt them to specific

tissues or circumstances. Some isozymes may enhance

survival by providing a backup copy of an essential

enzyme. Lactate dehydrogenase is a tetrameric enzyme

consisting of two monomer types- H (for heart) M (for

muscle) that combined to yield five LDH isozymes.

HHHH (I1), HHHM (I2), HHMM (I3), HMMM (I4),

Page 45: CURRICULUM VITAE Shagufta Moin, M.D. · comparative study 8. Dr. Puneet 2012 Comparative study of plasma ascorbic acid Parasurampuria and serum nitric oxide levels in senile cataract

MMMM (I5). Tissue- specific expression of H & M genes

determines the relative proportions of each subunit in

different tissues. Isozyme I1 predominates in heart tissue

& I5 in the liver. Thus, tissue injury releases a

characteristic pattern of LDH isozymes that can be

separated by electrophoresis. Creatine kinase (CK) has

three isozymes CK-MM (skeletal muscle), CK-BB (brain),

& CK-MB (heart & skeletal muscle). CK-MB appears

within 4-6 hours of an MI, peaks at 24 hours & returns to

base line by 48-72 hours. Individual CK isozymes are

separable by electrophoresis, thus facilitating detection.
