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 2.4.1.266 (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 3.1.3.85 (glucosyl-3-phosphoglycerate phosphatase).
