INTRODUCTION
Chaperones to work need a
previous function trigger factor
ensure that the protein is not
bad.
Chaperones are not just a class, there is
a variety that is more specialized
GroEL (E. coli)

• chaperones are a class of proteins that perform the folding of
proteins after their synthesis, three-
dimensional structure give.

chaperones have different families, these classifications are called chaperonins, GroEL is the one, and was discovered in E. Coli.
Chaperones GroEL helps when any protein can not fold while the folds 700 chaperone protein, GroEL alone the 1.
PROTEIN FOLDING: UNDERSTANDING THA DANCE OF THE CHAPERONES.
If not found GroEL, unfolded proteins accumulate, they generate long-term
problems, particularly neurodegenerative diseases.
OBSERVATION
I think the next step is to investigate the subtypes in
humans, we might have some more different than in the E. Coli easier to find
related pathologies accumulation of unfolded
proteins.

NEW INSIGHTS THE FUNCION OF MOLECULAR CHAPERONES
Chaperones act after synthesis, but
immediately after synthesis acts trigger factor.
NEW INSIGHTS THE FUNCION OF MOLECULAR CHAPERONES
prepares the trigger factor for subsequent
protein folding chaperones by,
besides avoiding premature folding
during the synthesis, making proteins
restricting erroneous.
NEW INSIGHTS THE FUNCION OF MOLECULAR CHAPERONES
The trigger factor also has a component repair, if a protein synthesis and ends has a premature folding factor reverses it, to make way for the
chaperones for proper maturation.
OBSERVATION
More important that these chaperones, the trigger is the determinant factor in the maturation of proteins in the protein deficiency
diseases and could be the point of treatment to
improve the condition.
Medical utility
MEDICAL UTILITY
PROTEIN FOLDING: UNDERSTANDING THE DANCE
OF THE CHAPERONES
know that the chaperones have the assistance of chaperonins like GroEL,
is one possible way to classify diseases related to protein
maturation, but still need to do research to determine the classes of
chaperones in humans and to investigate much more about them
as they can that the variation between human and E. Coli can be
bigger.
MEDICAL UTILITY
PROTEIN FOLDING: UNDERSTANDING THE DANCE OF THE CHAPERONES
In neurodegenerative diseases (Alzheimer and Parkinson diseases) should assess the role of chaperonins like GroEL
of E. Coli, if there is a deficiency of said chaperonin proteins accumulate which could not be folded by the
chaperone protein level causing cerebral plaques.

before a pathology level chaperones should be assessed first trigger
factor, because without chaperones would not
work, so they were structurally well.
