Question

Mark the INCORRECT statement about the enzyme carboxypeptidase.

• A. Zinc is the co-factor for this proteolytic enzyme
• B. It is exopeptidase
• C. It cleaves the peptide bond at N-terminal end of the polypeptide chain
• D. It is an enzyme of pancreatic juice

Answer 1

The correct option is C It cleaves the peptide bond at N-terminal end of the polypeptide chain

C. It cleaves the peptide bond at N-terminal end of the polypeptide chain

Solution : Carboxypeptidase are the group of exopeptidase that cleaves the C terminal of the peptide bonds. The carboxypeptidase as its name suggests attacks the C terminal of the peptides.

So the correct answer is " It cleaves the peptide bond at N-terminal end of the polypeptide chain".
