3.1.3.85 2-O-(alpha-D-glucopyranosyl)-3-phospho-D-glycerate + H2O - 3.1.3.85 2-O-(alpha-D-glucopyranosyl)-3-phospho-D-glycerate + H2O synthesis of the solute glucosylglycerate proceeds via a two-step pathway involving glucosyl-3-phosphoglycerate synthase (GpgS) and glucosyl-3-phosphoglycerate phosphatase (GpgP) 3.1.3.85 2-O-(alpha-D-glucopyranosyl)-3-phospho-D-glycerate + H2O in Persephonella marina two pathways for synthesis of glucosylglycerate are present: 1. the single-step pathway in with glucosylglycerate synthase (Ggs) catalyzes the synthesis of 2-O-(alpha-D-glucopyranosyl)-D-glycerate in one-step from ADP-glucose and D-glycerate, and 2. the two-step pathway in which glucosyl-3-phosphoglycerate synthase (GpgS) catalyzes the conversion of NDP-glucose and D-3-phosphoglycerate into glucosyl-3-phosphoglycerate, which is then converted to 2-O-(alpha-D-glucopyranosyl)-D-glycerate by glucosyl-3-phosphoglycerate phosphatase (GpgP)
