protease An enzyme that catalyses the hydrolysis of the peptide bonds of proteins and peptides. There are two types: endopeptidases (proteinases) primarily attack interior peptide bonds, while exopeptidases act on those adjacent to a free amino or carboxyl group.

protease (peptidase; proteinase; proteolytic enzyme) Any enzyme that catalyses the hydrolysis of proteins into smaller peptide fractions and amino acids, a process known as proteolysis. Examples are pepsin and trypsin. Several proteases, acting sequentially, are normally required for the complete digestion of a protein to its constituent amino acids. See also acid protease.
