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