Proteolytic Cleavage Has Been Shown to Be Involved in All

Question

Proteolytic cleavage has been shown to be involved in all of the following processes EXCEPT:
A) inactivation of regulatory enzymes.
B) elimination of the N-terminal Met residue.
C) activation of zymogens.
D) elimination of signal sequences after the protein has reached its proper location.
E) digestion of dietary proteins.

Accepted Answer

Proteolytic cleavage is involved in the activation of zymogens, elimination of the N-terminal Met residue, elimination of signal sequences after the protein has reached its proper location, and digestion of dietary proteins, but not in the inactivation of regulatory enzymes. Proteolytic cleavage typically activates or modifies proteins rather than inactivating them.
