Application
蛋白酶是一种可通过水解肽键来分解蛋白质的酶。蛋白酶可用于降解蛋白质、研究蛋白酶抑制剂以及研究热灭活动力学。产品P4630来自牛胰腺。来自牛胰蛋白酶（I型）的蛋白酶已被用于提取半纤维素。
Biochem/physiol Actions
蛋白酶可通过肽键的水解而使蛋白分解代谢。蛋白酶可被丝氨酸活性位点抑制剂所灭活，如苯甲基磺酰氟（PMSF）和二异丙基氟磷酸盐。
Analysis Note
粗品
Other Notes
除特殊声明，在 pH 7.5，37 °C条件下下，一单位在每分钟内可水解酪蛋白以生成与1.0 μ摩尔（181 μg）酪氨酸相当的颜色（颜色来自Folin-Ciocalteu试剂）。
