摩尔计算器

β-Galactosidase (EC 3.2.1.23)，即 β-半乳糖苷酶，是一种糖苷水解酶，可水解半乳糖与其有机部分之间形成的 β-糖苷键。在大肠杆菌中，lacZ 基因是 β-半乳糖苷酶的结构基因，可作为诱导系统lac操纵子的一部分。β-Galactosidase 可以水解乳糖形成葡萄糖和半乳糖，进入糖酵解；也可以催化乳糖转半乳糖基化为异乳糖；异乳糖可以裂解成单糖。

生物活性

β-Galactosidase (EC 3.2.1.23) is a glycoside hydrolase that hydrolyzes the β-glycosidic bonds formed between galactose and its organic moieties. In E.coli, the lacZ gene is the structural gene of β-galactosidase, which can be used as part of the induction system lac operon. β-Galactosidase can hydrolyze lactose to form glucose and galactose, and enter glycolysis; it can also catalyze the transgalactosylation of lactose into allolactose; allolactose can be cracked into monosaccharides[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
