應用
内切蛋白酶Glu-C（来自金黄色葡萄球菌 Staphylococcus aureus V8）已用于消化还原和烷基化环肽以生产线性片段。[1]
来自 Staphylococcus aureus菌株V8的内切蛋白酶Glu-C是一种丝氨酸蛋白酶，可用于蛋白质选择性切割，用来进行氨基酸序列确定或多肽图谱。 产品P2922用于线性化蝶豆叶子提取物[4]中的环状多肽。
生化／生理作用
在磷酸缓冲液中，Staphylococcus菌株V9蛋白酶特异性地切割多肽链天冬氨酸和谷氨酸残基的羧基侧。 当在碳酸氢铵缓冲液或醋酸铵中时，只切割谷氨酸残基的羧基侧。 该酶在pH4.0到7.8之间有最大活性。如果使用血红蛋白为底物，最大活性在pH4.0。 当酪蛋白为底物，最大活性在pH7.8。
單位定義
1单位酶可在pH7.8,37℃条件，每分钟水解1 μmole N-t-Boc--L-谷氨酸α-苯酯。[5]一单位相当于 ~0.004单位酪蛋白消化所需的酶量。

Common yet often overlooked, deamidation of peptidyl asparagine (Asn or N) generates aspartic acid (Asp or D) or isoaspartic acid (isoAsp or isoD). Being a spontaneous, non-enzymatic protein post-translational modification, deamidation artifact can be easily introduced during sample preparation, especially
