|
| Reaction(KEGG) |
|
| Substrate |
GDP-mannose [CPD: C00096];
3-phospho-D-glycerate [CPD: C00197]
|
| Product |

|
| Comment |
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.
