| Accepted name: |
glucosyl-3-phosphoglycerate phosphatase |
| Reaction: |
2-O-(α-D-glucopyranosyl)-3-phospho-D-glycerate + H2O = 2-O-(α-D-glucopyranosyl)-D-glycerate + phosphate |
| Other name(s): |
GpgP protein |
| Systematic name: |
α-D-glucosyl-3-phospho-D-glycerate phosphohydrolase |
| Comments: |
The enzyme is involved in biosynthesis of 2-O-(α-D-glucopyranosyl)-D-glycerate via the two-step pathway in which EC 2.4.1.266 (glucosyl-3-phosphoglycerate synthase) catalyses the conversion of GDP-glucose and 3-phospho-D-glycerate into 2-O-(α-D-glucopyranosyl)-3-phospho-D-glycerate, which is then converted to 2-O-(α-D-glucopyranosyl)-D-glycerate by glucosyl-3-phosphoglycerate phosphatase. In vivo the enzyme catalyses the dephosphorylation of 2-O-(α-D-mannopyranosyl)-3-phospho-D-glycerate with lower efficiency [1,2]. Divalent metal ions (Mg2+, Mn2+ or Co2+) stimulate activity [1,2]. |
