The presence of multiple types of β-galactosidases in a commercial enzyme preparation from Bacillus circulans ATCC 31382 and differences in their transgalactosylation activity were investigated. Four β-galactosidases, β-Gal-A, β-Gal-B, β-Gal-C, and β-Gal-D, which were immunologically homologous, wer...
