ADP-glucose + D-glycerate

2-O-(alpha-D-glucopyranosyl)-D-glycerate + ADP

Petrotoga mobilis

A9BEU2

the enzyme is involved in the nonphosphorylating pathway for synthesis of the solute mannosylglucosylglycerate. In Petrotoga mobilis two alternative pathways for the synthesis of the solute mannosylglucosylglycerate are proposed. The first one is a phosphorylating pathway (with a phosphorylated intermediate) from 3-phosphoglycerate and UDP-glucose to the final solute. The second nonphosphorylating pathway (no phosphorylated intermediates) could represent an alternative route for the synthesis of mannosylglucosylglycerate in Petrotoga mobilis that could lead to the direct conversion of glucosylglycerate and GDP-mannose to mannosylglucosylglycerate. Pathway multiplicity likely reflects a crucial role for mannosylglucosylglycerate in the physiology of Petrotoga mobilis during stress adaptation

ADP-glucose + glycerate

2-O-(alpha-D-glucopyranosyl)-D-glycerate + ADP

Persephonella marina

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-(alpha-D-glucosyl)-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-(alpha-D-glucopyranosyl)-D-glycerate by glucosyl-3-phosphoglycerate phosphatase (GpgP)
