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.

en·do·pep·ti·dase

(en'dō-pep'ti-dās),
An enzyme that catalyzes the hydrolysis of a peptide chain at points well within the chain, not near either terminus; for example, pepsin, trypsin. Compare: exopeptidase.
Synonym(s): proteinase

proteinase

/pro·tein·ase/ (pro´tēn-ās″) endopeptidase.

proteinase

(prōt′n-ās′, -āz′, prō′tē-nās′, -nāz′)
n.
An endopeptidase, such as pepsin, trypsin, or papain.

proteinase

[prō′tē·inās]
Etymology: Gk, proteios, first rank, ase, enzyme suffix
a proteolytic enzyme that splits protein molecules at central linkages. Also called tryptase.

proteinase

see ENDOPEPTIDASE.

protease

; proteinase enzyme that breaks down/proteolyses protein

proteinase

any enzyme that catalyzes the splitting of interior peptide bonds in a protein; an endopeptidase.

proteinase resistant protein (prp)
a protein which resists digestion by proteinases; the amyloid fibrils in brain tissue of sheep affected with scrapie contain such a prp.
