As an important medical enzyme, β-galactosidases catalyze transgalactosylation to form prebiotic Galacto-Oligosaccharides (GOS) that assist in improving the effect of intestinal flora on human health. In this study, a new glycoside hydrolase family 2 (GH2) β-galactosidase-encoding gene, galA, was cloned from the Antarctic bacterium Alteromonas sp. ANT48 and expressed in <i>Escherichia coli.</i> The recombinant β-galactosidase GalA was optimal at pH 7.0 and stable at pH 6.6-7.0, which are conditi ...[more]
