Chaperonin folding proteins flowchart
WebMay 27, 1997 · We propose a mechanism for the role of the bacterial chaperonin GroEL in folding proteins. The principal assumptions of the mechanism are (i) that many unfolded proteins bind to GroEL because GroEL preferentially binds small unstructured regions of the substrate protein, (ii) that substrate protein … WebAug 11, 1995 · The chaperonins GroEL and GroES of Escherichia coli facilitate protein folding in an adenosine triphosphate (ATP)-dependent reaction cycle. The kinetic parameters for the formation and dissociation of GroEL-GroES complexes were analyzed by surface plasmon resonance.
