In Petrotoga mobilis two alternative pathways for the synthesis of the rare solute 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 Petrotoga mobilis 2-O-[2-O-(alpha-D-mannopranosyl)-alpha-D-glucopyranosyl]-D-glycerate + phosphate - 410690 3.1.3.B8 2-O-[2-O-(alpha-D-mannopyranosyl)-alpha-D-glucopyranosyl]-3-phospho-D-glycerate + H2O - Rhodopirellula baltica DSM 10527 2-O-[2-O-(alpha-D-mannopranosyl)-alpha-D-glucopyranosyl]-D-glycerate + phosphate - 410690 3.1.3.B8 2-O-[2-O-(alpha-D-mannopyrarosyl)-alpha-D-glucopyranosyl]-3-phospho-D-glycerate + H2O - Rhodopirellula baltica 2-O-[2-O-(alpha-D-mannopyrarosyl)-alpha-D-glucopyranosyl]-D-glycerate + phosphate - 431328 3.1.3.B8 additional information UDP-glucose, ADP-glucose, GDP-mannose, ADP, GDP and UDP are dephosphorylated be the partially purified enzyme Petrotoga mobilis ? - 89 3.1.3.B8 additional information enzyme is non-specific for the mannosyl-donor, using GDP-mannose, UDP-mannose and ADP-mannose as substrates with decreasing affinity.
