IUBMB Enzyme Nomenclature


Accepted name: 1,2-α-glucosylglycerol phosphorylase

Reaction: 2-O-α-D-glucopyranosyl-glycerol + phosphate = β-D-glucose 1-phosphate + glycerol

Other name(s): 2-O-α-D-glucopyranosylglycerol phosphorylase

Systematic name: 2-O-α-D-glucopyranosyl-glycerol:phosphate β-D-glucosyltransferase

Comments: The enzyme has been isolated from the bacterium Bacillus selenitireducens. In the absence of glycerol the enzyme produces α-D-glucopyranose and phosphate from β-D-glucopyranose 1-phosphate. In this reaction the glucosyl residue is transferred to a water molecule with an inversion of the anomeric conformation.
