Stability of aminooxy glycosides to glycosidase catalysed hydrolysis

The stability of the amino(methoxy) beta-glycosidic bond to glycosidase catalysed hydrolysis is reported. Beta-O-benzyl glucose and beta-O-benzyl galactose are substrates hydrolysed by beta-glucosidase and beta-galactosidase from almonds and Escherichia coli, respectively. However their beta-N-benzyl-(Omethoxy)-glucoside and beta-N-benzyl-(O-methoxy)-galactoside derivatives are competitive inhibitors.

Solubilization, purification, and properties of membrane-bound D-glucono-δ-lactone hydrolase from Gluconobacter oxydans

Membrane-bound glucono-δ-lactonase (MGL) was purified to homogeneity from the membrane fraction of Gluconobacter oxydans IFO 3244. After solubilization with 1 M CaCl2, MGL was purified in the presence of Ca2+ and detergent. A single

Kinetics of Ru(III) Catalysed Oxidation of Aldoses by N-Bromosuccinimide in Aqueous Acetic Acid

The title reaction, studied in the presence of mercuric acetate, sulphuric acid and 10percent (v/v) acetic acid, is first order in both in the presence and absence of catalyst.However, the order in in the absence of catalyst, Ru(III) is unity which changes to fractional order in the presence of it.Increase in retards the reaction rate.The order of reactivities of different aldoses is: D-arabinose > D-xylose > D-galactose > D-mannose > D-glucose.Individual rate constants (k), formation constants (K) of the complex of aldoses and the catalyst and corresponding thermodynamic parameters have been evaluated and a suitable mechanism involving the α-anomer of aldose as the reactive substrate species has been suggested.
