Accepted name: glucosylglycerate synthase

Reaction: ADP-glucose + D-glycerate = 2-O-(α-D-glucopyranosyl)-D-glycerate + ADP

Other name(s): Ggs (gene name)

Systematic name: ADP-glucose:D-glycerate 2-α-D-glucosyltransferase

Comments: Persephonella marina possesses two enzymatic systems for the synthesis of glucosylglycerate. The first one is a single-step pathway in which glucosylglycerate synthase catalyses the synthesis of 2-O-(α-D-glucopyranosyl)-D-glycerate in one-step from ADP-glucose and D-glycerate. The second system is a two-step pathway in which EC (glucosyl-3-phosphoglycerate synthase) catalyses the conversion of NDP-glucose and 3-phospho-D-glycerate into 2-O-(α-D-glucopyranosyl)-3-phospho-D-glycerate, which is then converted to 2-O-(α-D-glucopyranosyl)-D-glycerate by EC (glucosyl-3-phosphoglycerate phosphatase).
