Accepted name: mannosylglycerate synthase
Reaction: GDP-α-D-mannose + D-glycerate = GDP + 2-O-(α-D-mannopyranosyl)-D-glycerate
Systematic name: GDP-α-D-mannose:D-glycerate 2-α-D-mannosyltransferase
Comments: Rhodothermus marinus can also form mannosylglycerate via a two-step pathway catalysed by EC (mannosyl-3-phosphoglycerate synthase) and EC (mannosyl-3-phosphoglycerate phosphatase) [1]. Depending on experimental conditions mannosylglycerate synthase is more or less specific for the GDP-mannose and D-glycerate [1,2].
