Question

Which of the following is a function of chaperone protein?

(a) It degrades proteins that have folded improperly

(b) It provide a template for how the proteins should fold

(c) It rescues proteins that have folded improperly and allows them to refold properly

(d) It degrades proteins that have folded properly

I got this question in an international level competition.

Asked question is from Protein Denaturation and Folding topic in portion Three Dimensional Structure Of Proteins and Protein Function of Biochemistry

Answer 1

Right choice is (c) It rescues proteins that have folded improperly and allows them to refold properly

The explanation: Molecular chaperons are proteins that interact with partially folded polypeptides, facilitating correct folding pathways in which folding can occur.
