1-O-Acetyl-beta-D-galactopyranose (AcGal), a new substrate for beta-galactosidase, was synthesized in a stereoselective manner by the trichloroacetimidate procedure. Kinetic parameters (K(M) and k(cat)) for the hydrolysis of 1-O-acetyl-beta-D-galactopyranose catalyzed by the beta-D-galactosidase from Penicillium sp. were compared with similar characteristics for

Alcohol substrate binding to the copper-containing enzyme galactose oxidase (GOase) has been studied by kinetic competition against cyanide and fluoride, 13C nmr relaxation, and esr competition experiments. The 13C nmr spectra of the substrate beta-O-methyl-D-galactopyranoside (beta-O-me-gal) show no apparent paramagnetic

PIP60-1, a novel heteropolysaccharide isolated from fruiting bodies of the medicinal fungus, Phellinus igniarius, has a molecular weight of 1.71 x 10(4)Da and is composed of L-fucose, D-glucose, D-mannose, D-galactose and 3-O-Me-D-galactose in a ratio of 1:1:1:2:1. A structural investigation

An arabinogalactan with a high content of 3-O-methyl-D-galactose residues has been isolated from the aerial parts of sage (Salvia officinalis L.). Structural studies of the polymer indicated a beta-1,6-D-galactopyranose backbone in which at least one-third of D-galactopyranosyl residues carries methoxyl
