产品介绍

产品介绍:

重组羧肽酶B专一水解蛋白质C-末端碱性氨基酸(赖氨酸、精氨酸、组氨酸),又称为肽酰-L-赖氨酸(L-精氨酸)水解酶;精蛋白酶。分子量为35kD,等电点为6.0,最适pH为7-9。活性受精氨酸、赖氨酸的竞争性抑制,金属离子螯合剂如EDTA等抑制酶活。 蛋白质C-末端碱性氨基酸如精氨酸、赖氨酸和组氨酸的测定。抗体碱性峰的检测。

定义:25℃,pH7.6,1min 催化 1μmol 马脲酰-L-精氨酸水解的酶量为一个酶活单位。

Carboxypeptidase B catalyzes hydrolysis of the basic amino acids lysine, arginine and histidine from the C-terminal end of polypeptides. The molecular weight is 34,500 daltons, the pH optimum is 8.0, and pI is 6.0. Carboxypeptidase B is competitively inhibited by arginine and lysine. The enzyme is also inhibited by metal chelating agents, e.g., EDTA. Recombinant Carboxypeptidase B is expressed in E.Coli and purified by high pressure liquid chromatography. There is no trace of other enzyme (such as carboxypeptidase A and chymotrypsin) activity. No protease inhibitors such as PMSF are present in the preparation.
Protein structure and sequence analysis, such as hydrolyze basic amino acids lysine, arginine and histidine from the C-terminal end of polypeptides. Antibody quality control
