Hydrolases;
Acting on peptide bonds (peptidases);
Cysteine endopeptidases
Reaction(IUBMB)
Hydrolysis of proteins with broad specificity for peptide bonds. Best reported small molecule substrate Bz-Phe-Val-Arg!NHMec, but broader specificity than fruit bromelain
Comment
From stem of pineapple plant, Ananas comosus. Differs from stem and fruit bromelains in being inhibited by chicken cystatin. In peptidase family C1 (papain family)
