Douglas Harper's Etymology Dictionary

1903, from protein + -ase. Related: Proteolysis.


n. (context enzyme English) An enzyme that cuts or cleaves proteins.


n. any enzyme that catalyzes the splitting of proteins into smaller peptide fractions and amino acids by a process known as proteolysis [syn: peptidase, proteinase, proteolytic enzyme]


A protease (also called a peptidase or proteinase) is any enzyme that performs proteolysis, that is, begins protein catabolism by hydrolysis of the peptide bonds that link amino acids together in a polypeptide chain. Proteases have evolved multiple times, and different classes of protease can perform the same reaction by completely different catalytic mechanisms. Proteases can be found in animals, plants, fungi, bacteria, archaea and viruses.
