Lactose and D-galactose metabolism in Staphylococcus aureus. II. Isomerization of D-galactose 6-phosphate to D-tagatose 6-phosphate by a specific D-galactose-6-phosphate isomerase.
The inducible D-galactose-6-phosphate isomerase that functions in the metabolism of lactose and D-galactose in Staphylococcus aureus was partially purified from extracts of D-galactose-grown cells. It was shown to catalyze specifically the reversible isomerization of D-galactose 6-phosphate to D-tagatose 6-phosphate, the apparent Km values being 9.6 mM and 1.9 mM, respectively. At equilibrium, ...
متن کاملUnveiling epimerization effects: a rotational study of α-D-galactose.
By studying its C4 epimer α-D-galactose, the effects of epimerization on the conformational behaviour of α-D-glucose have been unveiled. Using laser ablation of crystalline samples, four conformers of α-D-galactopyranose have been observed, for the first time, in a supersonic expansion by analyzing the Fourier transform rotational spectrum.
متن کاملThe D-galactose oxidase of Polyporus circinatus.
The mold Polyporus circinatus produces an extracellular oxidase that catalyzes the oxidation of n-galactose (1). The reaction appears superficially to be similar to the oxidation of n-glucose catalyzed by notatin (2)) and can be followed by measuring the consumption of oxygen or the production of Hz02 (1). The enzyme is useful for the determination of galactose, employing the same peroxidase-ch...
متن کامل6-Deoxy-6-fluoro-d-galactose
The crystal structure unequivocally confirms the relative stereochemistry of the title compound, C(6)H(11)FO(5). The absolute stereochemistry was determined by the use of d-galactose as the starting material. The compound exists as a three-dimensional O-H⋯O hydrogen-bonded network with each mol-ecule acting as a donor and acceptor for four hydrogen bonds.
متن کاملSoluble uridine diphosphate D-galactose: D-glucose beta-4-D-galactosyltransferase from bovine milk.
Some of the properties of a 70-fold purified bovine milk lactose synthetase have been determined. The enzyme preparation appears to be specific for uracil nucleoside diphosphate D-galactose derivatives. Adenosine, thymidine, @dine, or guanosine diphosphate derivatives cannot serve as galactosyl donors for n-glucose to form lactose. The enzyme preparation will not transfer the galactosyl residue...
