Related to alpha1-protease inhibitor: antitrypsin
any peptidase that catalyzes the cleavage of internal bonds in a polypeptide or protein. Inhibition of the action of endopeptidases (proteases) in viruses causes formation of noninfectious particles; certain antiviral drugs work in this way (see protease inhibitors). Called also protease and proteinase.

proteaseOne of a range of protein-splitting enzymes. One focus of current interest in proteases is in their role in breaking down tissue barriers in the spread of cancer. High concentrations of the activator of one of these proteases has been found to be associated with a poor outlook in cancers of the colon and rectum.
