应用

胃蛋白酶切割可用于产生抗体的F(ab′)2 片段。有关胃蛋白酶的更多信息，请访问 www.sigma-aldrich.com/enzymeexplorer。

生化/生理作用

优先裂解：P1 和 P1′ 位的疏水性和芳族残基。降解胰岛素 β 链中的 Phe-Val、Gln-His、Glu-Ala、Ala-Leu、Leu-Tyr、Tyr-Leu、Gly-Phe、Phe-Phe 和 Phe-Tyr 键

单位定义

1 个单位对应于在 pH 2.0 和 37℃ 下每分钟使 280 nm 处的吸光度增加 0.001 的酶量（血红蛋白，目录号 51290，作为底物）；上述 15,000 吸光度单位相当于约1 个 Bergmeyer 单位。一个Bergmeyer单位是在pH2.0和37℃下水解1 μmol乙酰基-L-苯基-3,5-二碘-L-酪氨酸的酶量。

分析说明

最适pH值为2-4。在4 M尿素和3 M盐酸胍中可保持活性。在60°C时稳定。胃蛋白酶在pH 8.0-8.5下发生不可逆灭活。

Swine pepsin at pH 5 efficiently catalyzes a condensation between Z-Ala-Ala-Phe-OH and p-nitroanilides of Leu, Phe, Val, Ala and Arg that leads to formation of corresponding benzyloxycarbonyl-tetrapeptide p-nitroanilides with yields of 70-90%. These reactions are complicated by co-precipitation of pepsin
