Exopeptidase

An exopeptidase is an enzyme produced in the pancreas that catalyses the removal of an amino acid from the end of a polypeptide chain. Exopeptidase cleaves the end of a polypeptide chain. Aminopeptidase, an enzyme in the brush border of the small intestine, will cleave a single amino acid from the aminoterminal. Carboxypeptidase, which is a digestive enzyme present in pancreatic juice, will cleave a single amino acid from the carboxylic end of the peptide.
