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
單位定義
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。
分析報告
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

Our previous report showed that yam dioscorin and its peptic hydrolysates exhibit radical scavenging activities; however, the functions of these peptic hydrolases are still under investigation. In this study, the thiol-containing peptides derived from computer-aided simulation of pepsin hydrolysis of

The African trypanosome Trypanosoma brucei, which persists within the bloodstream of the mammalian host, has evolved potent mechanisms for immune evasion. Specifically, antigenic variation of the variant-specific surface glycoprotein (VSG) and a highly active endocytosis and recycling of the surface
