Analysis Note
可能存在酰胺酶和酯酶活性
Application
羧肽酶Y具有广泛的特异性并且在尿素中稳定。因此，该酶与其他羧肽酶不同，可以用于序列分析。由于其酰胺酶作用，该酶可用于具有酰胺化COOH-末端基团的肽，例如催产素和加压素的序列分析。
Biochem/physiol Actions
糖蛋白的分子量约为61,000，氮含量为12.74％。它是一个含有442个残基的单条多肽链，在碳水化合物部分含有16个葡糖胺残基。赖氨酸位于NH2末端，-Asp-Ser-Thr-Leu位COOH末端序列。该酶的主要作用是从多肽链上去除COOH末端残基。它可用作液泡标记酶，用于蛋白质转运和定位研究。
Other Notes
基于EM/230 = 191.5，在25°C,pH 6.75的条件下，一个单位每分钟可将1.0 mole μN-CBZ-Phe-Ala水解为N-CBZ-L-苯丙氨酸和L-丙氨酸。
