Beta-galactosidase/GLB1 Protein, 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 is a hydrolase produced by Escherichia coli, which is widely found in natural plants. Beta-galactosidase is a tetrimer of four identical, abnormally long polypeptide chains, consisting of 9-10 subunits, with amino acid composition very different from that of Colithinase. Beta-galactosidase can be combined with Mg²⁺, Mn²⁺ and Na⁺. Beta-galactosidase is inhibited by phenethylthiobeta-d-galactose (PETG), isopropyl thiobeta-d-galactose (IPTG), L-ribose, d-galactolactone, lactose, and 2-amino-d-galactose. Beta-galactosidase has a large molecular weight and is easy to be isolated and purified. Beta-galactosidase can be used in food research^{[1][2][3][4][5]}.

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.
