Where Is Exopeptidase Found?

Exopeptidases are enzymes present with the gastrointestinal tract which cleave di- and tripeptides into their constituent amino acids. They differ from endopeptidases in that they target terminal peptide bonds. Both groups are peptidases.

Where is Exopeptidase produced?

The exocrine pancreas secretes three endopeptidases (trypsin, chymotrypsin, and elastase) and two exopeptidases (carboxypeptidase A and carboxypeptidase B) in inactive forms.

Where are endopeptidases found?

An endopeptidase (pepsin) is the only protein-digesting enzyme in the stomach. Only later, in the small intestine, is the food mixed with exopeptidases. Suggest the advantage of this sequence.
