溶菌酶(lyozyme LZM)是能分解革兰氏阳性细菌细胞壁缩氨酸聚糖分子中β-1,糖苷键的一组酶的总称,广泛存在于细菌、噬菌体、植物、动物和人体中。在本世纪初就有人发现鸡卵白具有分解细菌的能力,1922年Flem-ing认为许多生物组织及其分泌物都有分解细菌的活性物质,因此推测是一种酶,并起名叫溶菌酶或分解酶(Lytic Enzyme)。此后学者们对LZM进行分离纯化、氨基酸顺序分析以及酶学研究,终于弄清LZM是一种切断N-乙 Lysozyme (Lyozyme LZM) is a group of enzymes that break down β-1, glycosidic bonds in Gram-positive bacterial cell wall glycoprotein molecules and is widely found in bacteria, phages, plants, animals and humans. At the beginning of this century, chicken egg white was found to have the ability to break down bacteria. In 1922, Flemings considered that many biological tissues and their secretions have the activity of decomposing bacteria. Therefore, it is presumed to be an enzyme named lysozyme or decomposition Lytic Enzyme. Since then, scholars have carried out separation and purification of LZM, amino acid sequence analysis and enzymology research. Finally, it has been clarified that LZM is a peptide
