Character:
豬胰腺彈性酶是一種絲氨酸蛋白酶,它能水解氨基化合物和酯。彈性酶的特殊之處在于它能作用于彈性蛋白。酶作用的最佳pH值為8.5。大豆胰蛋白酶抑制劑和激肽釋放酶抑制劑能抑制其蛋白水解活性,但不能抑制其彈性蛋白水解活性。
彈性蛋白酶是從豬胰腺中分離提取的,并進一步用層析的方法制備,以去除殘留的其它蛋白酶的污染。 1 U corresponds to the amount of enzyme which liberates 1 μmol 4-nitroaniline per minute at 25°C and pH 7.8 (succinyl-(L-Ala)3-4-nitroanilide as substrate)
