The dried latex of the mountain papaya, Carica candamarcensis, was chromatographed on CM-Sephadex C50, giving rise to three peaks (CCI, CCII and CCIII) with amidase activity on N-alpha-benzoyl-DL-arginine-4-nitroanilide. The less basic, most active, peak, CCI, was separated into two components, CCIa
Kiwifruit contains the cysteine proteinase actinidin whose strong activity allows kiwifruit to be used as a meat tenderiser. This raises the possibility digestive enzymes, also proteins, are themselves susceptible to degradation by actinidin. Salivary amylase and gastric lipase are exposed to the
