General description
杏仁中发现的糖肽酶可分为 A、B 和 C 三组。糖肽酶 A 的最适 pH 值和等电点分别为 6.0 和 7.7。它偏爱长链糖肽。它还能够水解完整的糖蛋白，例如去唾液酸化的人转铁蛋白、卵清蛋白等。这些蛋白质在它们的 β-天冬氨酰-葡糖基胺键处切割具有去唾液酸碳水化合物部分的糖蛋白。
Application
来自杏仁的糖肽酶 A 用于去糖基化。它催化去除 N-连接的寡糖链并将 Asn 残基转化为 Asp。
Biochem/physiol Actions
水解 N4-(乙酰基-D-葡糖胺基)天冬酰胺，其中 N-乙酰基-D-葡糖胺残基可进一步糖基化，产生（取代的）N-乙酰基-β-D-葡糖胺基胺和含有天冬氨酸残基的肽。
Physical form
含 50 mM 柠檬酸盐-磷酸盐缓冲液（pH 5.0）和 BSA 的 50% 甘油溶液。
Other Notes
在 pH 5.0、37°C 条件下，1 个单位将每分钟水解1.0 μmole 卵清蛋白糖肽。

Proteome data of potato (Solanum tuberosum) tuber juice and of purified potato tuber vacuoles indicated that mature patatins may perhaps lack a C-terminal propeptide. We have confirmed this by complete mass spectrometric sequencing of a number of patatin variants as

The glycopeptidase preparation that has been isolated from almond emulsin and acts on beta-aspartylglycosylamine linkages in glycopeptides was separated into three active fractions by DEAE-cellulose column chromatography. The three discrete species of glycopeptidase (Groups A, B and C) have been
