alpha-D-glucosyl-3-phospho-D-glycerate phosphohydrolase

2-O-(alpha-D-glucopyranosyl)-3-phospho-D-glycerate + H2O = 2-O-(alpha-D-glucopyranosyl)-D-glycerate + phosphate [RN:R09664]

R09664
Reaction

2-O-(alpha-D-glucopyranosyl)-3-phospho-D-glycerate [CPD:C19791];
H2O [CPD:C00001]

The enzyme is involved in biosynthesis of 2-O-(alpha-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-(alpha-D-glucopyranosyl)-3-phospho-D-glycerate, which is then converted to 2-O-(alpha-D-glucopyranosyl)-D-glycerate by glucosyl-3-phosphoglycerate phosphatase. In vivo the enzyme catalyses the dephosphorylation of 2-O-(alpha-D-mannopyranosyl)-3-phospho-D-glycerate with lower efficiency [1,2]. Divalent metal ions (Mg2+, Mn2+ or Co2+) stimulate activity [1,2].
