endopeptidase

Any of a large group of enzymes that catalyze the hydrolysis of peptide bonds in the interior of a polypeptide chain or protein molecule.

Enzymes that hydrolyse proteins (i.e. proteinases or peptidases), by cleaving peptide bonds within the protein chain, as opposed to exopeptidases, which remove amino acids from the end of the chain. The main endopeptidases in digestion are chymotrypsin, elastase, pepsin, and trypsin.

Any of a large group of enzymes that catalyze the hydrolysis of peptide bonds in the interior of a polypeptide chain or protein molecule.

A peptidase capable of acting on any peptide linkage in a peptide chain.
