A) two residues on the C-terminal end
B) two residues on the N-terminal end
C) three residues on the N-terminal end
D) three residues on the C-terminal end
E) six residues on the N-terminal end
Carboxypeptidase
An enzyme that catalyzes the hydrolysis of the carboxyl-terminal (C-terminal) peptide bond in a protein or peptide.
Sequence Information
Refers to the order of units (such as nucleotides in nucleic acids or amino acids in proteins) within a macromolecule, critical for determining its function and properties.
- Describe the process of deriving amino acid sequence data from proteins and peptides.

Final Answer :
A
Explanation :
Carboxypeptidase specifically cleaves amino acids from the C-terminal end of a protein or peptide chain, but its practical use for sequencing is generally limited to identifying only the last one or two amino acids due to its decreasing efficiency as it moves further from the end.
