IUBMB Enzyme Nomenclature


Accepted name: glucosylglycerol phosphorylase (configuration-retaining)

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

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

Systematic name: 2-O-α-D-glucopyranosyl-glycerol:phosphate α-D-glucosyltransferase (configuration-retaining)

Comments: The enzyme, characterized from the halotolerant bacterium Marinobacter adhaerens, is likely responsible for degradation of the compatible solute 2-O-α-D-glucopyranosyl-glycerol when the environmental salt concentration decreases. cf. EC, 1,2-α-glucosylglycerol phosphorylase.
