    2.4.1.266 | GDP-glucose + 3-phospho-D-glycerate |
synthesis of the solute glucosylglycerate proceeds via a two-step pathway involving glucosyl-3-phosphoglycerate synthase (GpgS) and glucosyl-3-phosphoglycerate phosphatase (GpgP). An mpgS gene coding for mannosyl-3-phosphoglycerate synthase (MpgS) is absent |
| 2.4.1.266 | more |
the genes for glucosyl-3-phosphoglycerate synthase, GpgS, and glucosyl-3-phosphoglycerate phosphatase, GpgP, the enzymes that lead to the synthesis of glucosylglycerol through the formation of glucosyl-3-phosphoglycerate, are organized in anoperon-like structure with the gene encoding a putative glycosyltransferase, the glucosylglycerate synthase, Ggs, overview, biosynthetic pathway overview |

key enzyme of glucosylglycerate synthesis |
| 2.4.1.266 | UDP-glucose + 3-phospho-D-glycerate |
the enzyme is involved in the phosphorylating pathway for synthesis of the solute mannosylglucosylglycerate. In Petrotoga mobilis two alternative pathways for the synthesis of mannosylglucosylglycerate are proposed. The first one is a 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 mobilis during stress adaptation |
| 2.4.1.266 | UDP-glucose + 3-phospho-D-glycerate |
involved in biosynthesis of methylated polysaccharides |
| 2.4.1.266 | UDP-glucose + 3-phospho-D-glycerate |
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-glucosyl)-D-glycerate in one-step fop, 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-glucosyl)-D-glycerate by glucosyl-3-phosphoglycerate phosphatase (GpgP) |
