NHMec, but broader specificity than fruit bromelain
Reaction: Hydrolysis of proteins with broad specificity for peptide bonds. Best reported small molecule substrate Bz-Phe-Val-ArgNHMec, but broader specificity than fruit bromelain
Other name(s): stem bromelain; fruit bromelain
Comments: 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)
