猪笼草蛋白酶

猪笼草蛋白酶NepenthesinNepenthacin[1][2]Nepenthasin[3]),又称猪笼草酸性蛋白酶猪笼草天冬氨酸蛋白酶[3]猪笼草捕虫笼盾叶茅膏菜Drosera peltata分泌的天冬氨酸蛋白酶[4][5][6][7][8][9]其与胃蛋白酶类似,但其也能酶切两侧的天冬氨酸残基及赖氨酸精氨酸[3]其对pH值及温度的稳定性高于猪胃蛋白酶A,对尿素盐酸胍的稳定性大大降低。[10]

1968年,Shigeru Nakayama和Shizuko Amagase以“nepenthesin”命名猪笼草蛋白酶。[11]在猪笼草属中已确定了2个同工酶:猪笼草蛋白酶I猪笼草蛋白酶II[12]
