Function
catalytic activity:3-phospho-D-glyceroyl phosphate + alpha-D-glucose 1-phosphate = 3-phospho-D-glycerate + alpha-D-glucose 1,6-bisphosphate.,function:Glucose 1,6-bisphosphate synthase using 1,3-bisphosphoglycerate as a phosphate donor and a series of 1-phosphate sugars as acceptors, including glucose 1-phosphate, mannose 1-phosphate, ribose 1-phosphate and deoxyribose 1-phosphate. 5 or 6-phosphosugars are bad substrates, with the exception of glucose 6-phosphate. Also synthesizes ribose 1,5-bisphosphate. Has only low phosphopentomutase and phosphoglucomutase activities.,similarity:Belongs to the phosphohexose mutase family.,
