Practice question
Question
The enzyme that specifically removes the N-terminal amino acid from a peptide is:
Explanation
Aminopeptidase is the accurate response regarding enzymatic activity or regulation described in this question. Enzymes are biological catalysts that accelerate reactions by lowering activation energy through specific substrate binding and transition state stabilization. In the context of Protein Degradation, Aminopeptidase plays a specific catalytic or regulatory role determined by its active site configuration and mechanism of action. The other options (Trypsin, Carboxypeptidase, and Chymotrypsin) are either different enzymes with distinct substrate specificities, act through different mechanisms, or are involved in separate metabolic pathways.
