What is the substrate of exopeptidase?

Answer:An exopeptidase activity was originally identified in several rat tissues [1], using L-aminoacyl β-naphthylamides (L-aa β-NA) and L-amino acid-7-amido-4-methylcoumarins as substrates.

Explanation:This enzyme was able to remove only basic residues (Arg and Lys) from L-aa β-NA and was consequently called aminopeptidase B.

Substrate:Smaller polypeptides

Products:Amino acids; Dipeptides
