Application

来自拟葡萄球菌的溶葡球菌酶被用于评估lytM（一种独特的金黄色葡萄球菌自溶基因）的分子克隆、测序和表达。 它还被用于研究金黄色葡萄球菌中编码肽聚糖水解酶活性的基因的序列分析。

Biochem/physiol Actions

一种蛋白复合体，对葡萄球菌属（包括金黄色葡萄球菌）具有高度特异性裂解活性。
溶葡萄球菌酶具有抗金黄色葡萄球菌的裂解作用，可用于治疗耐抗生素的葡萄球菌感染。它具有甘氨酰甘氨酸内肽酶、内-β-N-乙酰葡萄糖胺酶和N-乙酰胞壁酰-L-丙氨酸酰胺酶等多种酶的特性。溶葡萄球菌酶还可用于食品防腐和临床实验室的快速筛查。
通过与金黄色葡萄球菌的膜相关Trap蛋白的C′ 端结合，溶葡球菌酶（金黄色葡萄球菌表达的一种金属内肽酶）的抗微生物活性得到增强。

General description

溶葡萄球菌酶是一种锌金属酶，主要以酶原的形式分泌出来。它可用作抗金黄色葡萄球菌剂，在pH4和5℃时高度稳定。

A gene encoding an autolytic activity was identified in an autolysis-deficient mutant (Lyt-) of Staphylococcus aureus which produces only a single band in autolytic-activity gels (N. Mani, P. Tobin, and R. K. Jayaswal, J. Bacteriol. 175:1493-1499, 1993). An open reading
