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.
在大猪笼草的分泌液中至少存在两种蛋白酶，其中一种主要蛋白酶的分子量估计为 59000，另一种次要蛋白酶的分子量为 21000。主要酶（猪笼草凝乳酶）的特异性比之前报道的更广泛，与胃蛋白酶惊人地相似。还证明了脂肪酶的活性，而不存在淀粉酶的活性。
