一般描述
从 链霉菌 中提取的变溶菌素由两种主要的裂解酶组成,可能是一种有效的龋病防治剂。
应用
为从细菌分离中易于降解的生物分子和RNA提供了温和的细胞裂解。 它已可用于形成球状体以分离DNA。
生化/生理作用
变溶菌素可切开细菌细胞壁中肽聚糖-多糖聚合物的β-N-乙酰胞壁酸-(1→4)-N-乙酰葡糖胺的连键。可裂解李斯特菌和其他革兰氏阳性菌,如乳杆菌属和乳球菌属。
变溶菌素是一种N-乙酰胞壁质酶。同溶菌酶一样是一种胞壁水解酶,可切开细菌细胞壁中肽聚糖-多糖聚合物的β-N-乙酰胞壁酸-(1→4)-N-乙酰葡糖胺的连键。其羧基末端部分参与识别和结合独特的细胞壁聚合物。变溶菌素可裂解李斯特菌和其他革兰氏阳性菌,如乳杆菌属和乳球菌属。
单位定义
以粪链球菌细胞壁混悬液为底物,在1mL体积中,1单位变溶菌素在pH 6.0、37 °C条件下每分钟可产生0.01的ΔA600 。
