Sysname
2,3-bisphospho-D-glycerate 3-phosphohydrolase
Reaction(IUBMB)
2,3-bisphospho-D-glycerate + H2O = 2-phospho-D-glycerate + phosphate [RN:R09532]
Reaction(KEGG)
Substrate
2,3-bisphospho-D-glycerate [CPD:C01159];
H2O [CPD:C00001]
Product
2-phospho-D-glycerate [CPD:C00631];
phosphate [CPD:C00009]
Comment
This reaction is a shortcut in the Rapoport-Luebering shunt. It bypasses the reactions of EC 3.1.3.13/EC 5.4.2.12 [bisphosphoglycerate phosphatase/phosphoglycerate mutase (2,3-diphosphoglycerate-independent)] and directly forms 2-phospho-D-glycerate by removing the 3-phospho-group of 2,3-diphospho-D-glycerate [1]. The MIPP1 protein also catalyses the reaction of EC 3.1.3.62 (multiple inositol-polyphosphate phosphatase).
