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。

Secretion of proteins in Gram-negative bacteria is a high-energy-consuming process that requires translocation across two membranes and a periplasmic space composed of a mesh-like layer, the peptidoglycan. To achieve this, bacteria have evolved complex secretion systems that cross these barriers

Yersinia pestis (the plague bacillus) and its ancestor, Yersinia pseudotuberculosis (which causes self-limited bowel disease), encode putative homologues of the periplasmic lysozyme inhibitor Ivy and the membrane-bound lysozyme inhibitor MliC. The involvement of both inhibitors in virulence remains subject to

G-protein-coupled receptors (GPCRs) represent a major class of receptors through which a number of signals ranging from photons to large glycoprotein hormones are recognized. Human genome encodes about 800 GPCRs, yet very little structural information is available on this class

Neutrophils are considered responsible for the pathophysiologic changes during hepatic ischemia-reperfusion (I/R) injury; however, few studies have examined real-time intravital neutrophil recruitment. Here, we show a method for imaging the neutrophil recruitment in hepatic I/R injury using two-photon laser scanning
实验方案
This enzymatic rate determination may be used for Lysozyme products. It is not to be used to assay recombinant or insoluble Lysozyme on agarose.
