Summary:
The Rapoport-Luebering glycolytic shunt, which has been documented in Dictyostelium, birds and mammals, generates and dephosphorylates 2,3-diphospho-D-glycerate (2,3-BPG) [Kauffman02, Rapoport77].

The enzyme that generates 2,3-BPG is the bifunctional bisphosphoglycerate mutase. The enzyme converts the glycolytic intermediate 1,3-bisphospho-D-glycerate (1,3-BPG) to 2,3-BPG, and also acts as a phosphatase, converting 2,3-BPG to 3-phospho-D-glycerate (3-PG), which then reenters the main glycolytic pathway.

During the standard glycolysis pathway 1,3-BPG is converted to 3-PG in a single step, generating an ATP molecule, and by directing 1,3-BPG to the Rapoport-Luebering shunt the cell gives up the production of this ATP molecule. However, the purpose of this shunt is the production of 2,3-BPG, which is a key regulator in the cell.

First, 2,3-BPG fulfills an essential role in glycolysis by priming the phosphoglycerate mutase reaction that converts 3-PG to 2-phospho-D-glycerate (2-PG) [FothergillGilmo93]. In addition, 2,3-BPG provides a molecular link between the turnover of phosphorylated inositol derivatives and glycolytic flux, being a regulator of key enzymes such as type I inositol-1,4,5-trisphosphate 5-phosphatase [Downes82] and phosphatidylinositol-3,4,5-trisphosphate 5-phosphatase 1 [Drayer96].

Finally, 2,3-BPG is a key regulator of oxygen release from erythrocytes, by preferentially binding to deoxyhemoglobin [Benesch67, Benesch68].

Recently a new enzyme activity in this pathway has been discovered [Cho08a]. 2,3-bisphosphoglycerate 3-phosphatase catalyzes the direct production of 2-PG from 2,3-BPG, bypassing phosphoglycerate mutase. The enzyme that catalyzes this activity, which is encoded by the MINPP1 gene, has been previously known as multiple inositol polyphosphate phosphatase 1, and thus 2,3-bisphosphoglycerate 3-phosphatase is a new activity attributed to it. The enzyme from Dictyostelium discoideum has been characterized, and total activity in erythrocytes was equivalent to the level of the phosphatase activity of 2,3-BPG synthase/2-phosphatase [Cho08a].
