Which of the Following is NOT an Example of a Heat-Shock

Question

Which of the following is NOT an example of a heat-shock protein?
A) trigger factor
B) GroES
C) GroEL
D) Clp protease
E) DnaK

Accepted Answer

Clp protease is not a heat-shock protein. Instead, it is a family of proteases that are involved in degradation of specific proteins. The other options, trigger factor, GroES, GroEL, and DnaK, are all examples of heat-shock proteins that are involved in protein folding and refolding.
