This reaction is a shortcut in the Rapoport-Luebering shunt. It bypasses the reactions of EC 188.8.131.52/EC 184.108.40.206 [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 . The MIPP1 protein also catalyses the reaction of EC 220.127.116.11 (multiple inositol-polyphosphate phosphatase).
