proteinase

endopeptidase

 [en″do-pep´tĭ-dās]

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.
