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.

Soybean meal is the most important plant protein source currently used to supplement feed for cultured shrimp, but it cannot be used as the sole source of protein because it lacks certain essential amino acids and contains antinutritional factors such as lectins and proteinase inhibitors (Cordova Murueta and Garcia Carreno, 2002).
