An exopeptidase is any peptidase that catalyzes the cleavage of the terminal (or the penultimate) peptide bond; the process releases a single amino acid or dipeptide from the peptide chain. Depending on whether the amino acid is released from the amino or the carboxy terminal, an exopeptidase is further classified as an aminopeptidase or a carboxy...
A hydrolase enzyme that removes the end amino acids of a polypeptide by cleaving peptide bonds. ... (09 Oct 1997) ... 
(ek″so-pep´tĭ-dās) a proteolytic enzyme whose action is limited to terminal peptide linkages.
Enzyme that cleaves amino acid residues from one or other end of a protein chainPeptide hydrolases of the class EC3.4 that cleave the N- or C-terminal amino acid from a peptide.
Type: Term Pronunciation: ek′sō-pep′ti-dās Definitions: 1. An enzyme that catalyzes the hydrolysis of the terminal amino acid of a peptide chain; carboxypeptidase.
Exopeptidase: An enzyme that catalyzes the cleavage of the terminal (last) or next-to-last peptide bond from a polypeptide or protein, releasing a single amino acid or dipeptide. By contrast, an endopeptidase catalyzes the cleavage of then internal peptide bonds within a polypeptide or protein.
