Beta-galactosidase/GLB1 蛋白, E.coli

Beta-galactosidase/GLB1 protein is a hydrolase with catalytic activity and binding sites of Mg²⁺, Mn²⁺ and Na⁺. Beta-galactosidase/GLB1 protein can be used for research in genetics, molecular biology, and other life sciences. Beta-galactosidase/GLB1 Protein, E.coli is the recombinant E. coli-derived Beta-galactosidase/GLB1 protein, expressed by E. coli , with tag free. The total length of Beta-galactosidase/GLB1 Protein, E.coli is 1024 a.a., with molecular weight of ~115.0 kDa.

Beta-galactosidase 是一种广泛存在于自然界植物中可由大肠杆菌产生的水解酶。Beta-galactosidase由四条相同的、异常长的多肽链组成的四聚体，有 9-10 个亚基组成，氨基酸组成和大肠杆菌酶有很大不同。Beta-galactosidase 可与Mg²⁺、Mn²⁺ 和Na⁺ 结合。Beta-galactosidase 可被苯乙基硫代-β-D-半乳糖(PETG)、异丙基硫代-β-D-半乳糖(IPTG)、L-核糖、D-半乳糖内酯、乳糖和2-氨基-D-半乳糖抑制。Beta-galactosidase 具有较大的分子量，易于分离纯化。Beta-galactosidase 可用于食品方面的研究。
