Epilactose (4-O-beta-galactopyranosyl-D-mannnose) is a rare disaccharide in cow milk that can be synthesized from lactose by the cellobiose 2-epimerase of Ruminococcus albus. In this study, we examined the biological activities of epilactose using male Wistar-ST rats. The apparent rates of

The regioselectivity of beta-galactosidase derived from Bacillus circulans ATCC 31382 (beta-1,3-galactosidase) in transgalactosylation reactions using D-mannose as an acceptor was investigated. This D-mannose associated regioselectivity was found to be different from reactions using either GlcNAc or GalNAc as acceptors, not

The combined effects of temperature (60 degrees C) and high-pressure treatments (400 MPa for 3 h) on the isomerization-degradation of lactose (10%) in basic media were studied. The formation of isomeric disaccharides (lactulose and epilactose) and galactose decreased by the

A practical purification method for a non-digestible disaccharide, epilactose (4-O-beta-galactosyl-D-mannose), was established. Epilactose was synthesized from lactose with cellobiose 2-epimerase and purified by the following procedure: (i) removal of lactose by crystallization, (ii) hydrolysis of lactose by beta-galactosidase, (iii) digestion

The wbsJ gene from Escherichia coli O128:B12 encodes an alpha1,2-fucosyltransferase responsible for adding a fucose onto the galactose residue of the O-antigen repeating unit via an alpha1,2 linkage. The wbsJ gene was overexpressed in E. coli BL21 (DE3) as a
