• 介绍：

  分子量：14300。

  活力：≥20000u/mg。

  适宜pH:5.3～6.4。

  来源：鸡蛋清。

  性状：粉末。

  由18种129个氨基酸残基构成的单一肽链。它富含碱性氨基酸，有4对二硫键维持酶构型，是一种碱性蛋白质，其N端为赖氨酸，C端为亮氨酸。蛋清溶菌酶是C型，是已知的最耐热的酶。

  活力定义：一个溶菌酶活力单位定义为 25℃ ,pH6. 2 条件下,使用藤黄微球菌悬浊液在 450nm 处每分钟引起吸光度变化为 0.001 所需溶菌酶的量。

• 储存条件： 2-8℃

• 用途： 是一种能水解致病菌中黏多糖的碱性酶。主要通过破坏细胞壁中的N-乙酰胞壁酸和N-乙酰氨基葡糖之间的β-1,4糖苷键，使细胞壁不溶性黏多糖分解成可溶性糖肽，导致细胞壁破裂内容物逸出而使细菌溶解。溶菌酶还可与带负电荷的病毒蛋白直接结合，与DNA、RNA、脱辅基蛋白形成复盐，使病毒失活。可分解溶壁微球菌、巨大芽孢杆菌、黄色八叠球菌等革兰阳性菌。
