IUBMB Enzyme Nomenclature


Accepted name: glucosylglycerol-phosphate synthase

Reaction: ADP-α-D-glucose + sn-glycerol 3-phosphate = 2-(α-D-glucopyranosyl)-sn-glycerol 3-phosphate + ADP

Other name(s): ADP-glucose:sn-glycerol-3-phosphate 2-β-D-glucosyltransferase (incorrect)

Systematic name: ADP-α-D-glucose:sn-glycerol-3-phosphate 2-α-D-glucopyranosyltransferase

Comments: Acts with EC (glucosylglycerol phosphatase) to form glucosylglycerol, an osmolyte that endows cyanobacteria with resistance to salt.
