摘要：

An Arthrobacter beta-galactosidase has homolog with the lysosomal acid beta-galactosidases from humans and mice and with a Xanthomonas manihotis enzyme, Phylogenetic analysis of the deduced amino acid sequence showed an unusual pattern, with this procaryotic enzyme clustering within the animal clade, The gene encodes a subunit of 52 kDa, and the enzyme appears to be active as a dimer. The enzyme hydrolyzed substrates with either a beta-1,4 or a beta-1,3 linkage.
