应用

酶可分解细菌的细胞壁;用于制备原生质体。

生化/生理作用

溶菌酶可水解肽聚糖中N-乙酰胞壁酸与N-乙酰-D-氨基葡萄糖残基之间以及壳糊精中N-乙酰-D-氨基葡萄糖残基之间的β(1→4)连接。 革兰氏阳性细胞对这种水解非常敏感,因为它们的细胞壁中的肽聚糖比例很高。革兰氏阴性菌就对这种水解没那么敏感,因为它们有外膜并且肽聚糖的比例较低。然而,这些细胞可能在细胞外膜中螯合金属离子的EDTA存在的情况下水解。

该酶在广泛的pH范围(6.0至9.0)内具有活性。pH值为6.2时,可在更广的离子强度范围(0.02至0.100 M)观察到最大活性,而pH值为9.2时为0.01至0.06 M。

单位定义

在pH 7.0和25℃条件下,1 U对应于每分钟使450 nm处的吸光度降低0.001的酶量(藤黄微球菌,ATCC 4698,作为底物)
