Functional metagenomics reveals novel β-galactosidases not predictable from gene sequences. [PDF]
PLoS ONE, 2017 The techniques of metagenomics have allowed researchers to access the genomic potential of uncultivated microbes, but there remain significant barriers to determination of gene function based on DNA sequence alone.

A novel Arthrobacter beta-galactosidase with homology to eucaryotic beta-galactosidases
Journal of Bacteriology, 1997 An Arthrobacter beta-galactosidase has homology 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.

α-Galactosidases and their applications in biotransformations
, 2009 α-d-Galactosidases (α-d-galactoside galactohydrolase, E.C. 3.2.1.22) are exoglycosidases, which in vivo catalyze the hydrolysis of simple and complex oligo- and polysaccharides containing terminal α-d-galactosyl groups.
