EC 3.1.3.85

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].
