EC 3.1.3.80     
Accepted name: 2,3-bisphosphoglycerate 3-phosphatase
Reaction: 2,3-bisphospho-D-glycerate + H2O = 2-phospho-D-glycerate + phosphate
Other name(s): MIPP1; 2,3-BPG 3-phosphatase
Systematic name: 2,3-bisphospho-D-glycerate 3-phosphohydrolase
Comments: This reaction is a shortcut in the Rapoport-Luebering shunt. It bypasses the reactions of EC 5.4.2.11/EC 5.4.2.12 [phosphoglycerate mutases (2,3-diphosphoglycerate-dependent and 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).
