一般說明
内蛋白酶赖氨酸-碳测序等级是从产酶溶血杆菌中分离出来的，是一种高度纯化和特异的蛋白酶。来自产酶溶杆菌的内切蛋白酶 Lys-C是肽酶S1家族的一员。它主要用于蛋白质序列分析中多肽链的初始断裂。
特異性
这种酶是一种丝氨酸蛋白酶，能特异性水解赖氨酸羧基侧的酰胺、酯和肽键（在三-盐酸缓冲液中，pH 7.0至9.0）。
热失活：酶可以通过加热（100℃下5分钟）或TCA变性。
热失活：酶可以通过加热（100℃下5分钟）或TCA变性。
應用
使用内蛋白酶赖氨酸-碳测序等级进行蛋白质结构分析和序列分析。它适用于消化溶液、聚丙烯酰胺凝胶或吸水膜中的蛋白质。
準備報告

Tandem mass (MS/MS) spectra generated by collision-induced dissociation (CID) typically lack redundant peptide sequence information in the form of e.g. b- and y-ion series due to frequent use of sequence-specific endopeptidases cleaving C- or N-terminal to Arg or Lys residues.

This protocol outlines the essential steps of mass spectrometry-based analysis of protein samples that can be used to identify post-translational arginylation. We describe special considerations for sample preparation and digestion, mass spectrometry analysis using high-precision instruments, database searching for the
