At least two proteases are present in the secretion of the pitchers of Nepenthes macferlanei, a major one with an estimated molecular weight of 59000 and a minor one of 21000. The specificity of the major enzyme, nepenthesin, was broader than previously reported, and strikingly similar to that of pepsin. Lipase activity was also demonstrated, while no amylase activity was present.
