Application
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中的环状多肽。
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。
它可用于蛋白质选择性切割以便进行氨基酸序列测定或肽谱分析。
Biochem/physiol Actions
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。
Other Notes
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。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

Protein phosphorylation is a reversible post-translational modification known to regulate protein function, subcellular localization, complex formation, and protein degradation. Detailed phosphoproteomic information is critical to kinomic studies of signal transduction and for elucidation of cancer biomarkers, such as in non-small-cell
