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 18.104.22.168 (mannosyl-3-phosphoglycerate synthase) and EC 22.214.171.124 (mannosyl-3-phosphoglycerate phosphatase) . Depending on experimental conditions mannosylglycerate synthase is more or less specific for the GDP-mannose and D-glycerate [1,2].
