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。
纯化的变溶菌素SAE0092已经过严格的质量控制测试，以确保通过35个循环对16S和18S rDNA（使用通用引物对）进行PCR扩增时，不存在可检测水平的污染DNA。
变溶菌素是一种胞壁溶解酶，适合分离来自革兰氏阳性菌（如李斯特菌、乳杆菌、乳球菌）(8)和其他仅用溶菌酶难以裂解的细菌。

生化/生理作用
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。
特点和优势
适用于难以裂解的样品。
无微生物DNA，最大限度地减少工作流程中试剂对DNA的污染。
适用于从革兰氏阳性菌中分离核酸，包括李斯特菌、乳酸杆菌和乳球菌。

Group B streptococci, refractory to previously tested muralysins under physiological conditions, were successfully converted to protoplasts by use of a recently describede N-acetyl muramidase, mutanolysin, derived from a streptomycete. Purified enzyme was effective, but crude preparations, although degrading cell walls
