Accepted name: mannosylglucosyl-3-phosphoglycerate synthase
Reaction: GDP-mannose + 2-O-(α-D-glucopyranosyl)-3-phospho-D-glycerate = GDP + 2-O-[2-O-(α-D-mannopyranosyl)-α-D-glucopyranosyl]-3-phospho-D-glycerate
Other name(s): MggA
Systematic name: GDP-mannose:2-O-(α-D-glucosyl)-3-phospho-D-glycerate 2-O-α-D-mannosyltransferase
Comments: The enzyme is involved in synthesis of 2-[2-O-(α-D-mannopranosyl)-α-D-glucopyranosyl]-D-glycerate. Petrotoga miotherma and Petrotoga mobilis accumulate this compound in response to water stress imposed by salt.
