chymase


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

chy·mo·sin

(kī'mō-sin),
An aspartic proteinase structurally homologous with pepsin, formed from prochymosin; the milk-curdling enzyme obtained from the glandular layer of the stomach of the calf. Acts on a single peptide bond (-Phe-Met-) in κ-casein.
Synonym(s): chymase, pexin, rennase, rennet, rennin

chymase

(kī′mās)
An enzyme in gastric juice that accelerates the action of the pancreatic enzymes.

chymase

see RENNIN.
