Accepted name: |
mannosyl-3-phosphoglycerate synthase |
Reaction: |
GDP-mannose + 3-phospho-D-glycerate = GDP + 2-(α-D-mannosyl)-3-phosphoglycerate |
Other name(s): |
MPG synthase; GDP-mannose:3-phosphoglycerate 3-α-D-mannosyltransferase |
Systematic name: |
GDP-mannose:3-phospho-D-glycerate 3-α-D-mannosyltransferase |
Comments: |
Requires Mg2+. The enzyme is absolutely specific for GDPmannose and 3-phosphoglycerate, and transfers the mannosyl group with retention of configuration. In the hyperthermophilic archaeon Pyrococcus horikoshii, the mannosyl-3-phosphoglycerate formed is subsequently dephosphorylated by a specific phosphatase, EC 3.1.3.70 (mannosyl-3-phosphoglycerate phosphatase), producing mannosylglycerate. |
