In the direction shown, this enzyme is phosphorylated by 3-phosphoglyceroyl phosphate, to give phosphoenzyme and 3-phosphoglycerate. The latter is rephosphorylated by the enzyme to yield 2,3-bisphosphoglycerate, but this reaction is slowed by dissociation of 3-phosphoglycerate from the enzyme, which is therefore more active in the presence of added 3-phosphoglycerate. This enzyme also catalyses, slowly, the reaction of EC 5.4.2.11 [phosphoglycerate mutase (2,3-diphosphoglycerate-dependent)] and EC 5.4.2.12 [phosphoglycerate mutase (2,3-diphosphoglycerate-independent)].

3-Phospho-D-glycerate 1,2-phosphomutase
In the direction shown, this enzyme is phosphorylated by 3-phosphoglyceroyl phosphate, to give phosphoenzyme and 3-phosphoglycerate. The latter is rephosphorylated by the enzyme to yield 2,3-bisphosphoglycerate, but this reaction is slowed by dissociation of 3-phosphoglycerate from the enzyme, which is therefore more active in the presence of added 3-phosphoglycerate.

multifunctional enzyme for synthesis and degradation of 2,3-diphosphoglycerte, additional activities are diphosphoglycerate phosphatase and phosphoglycerate mutase
in red blood cells 2,3-diphosphoglycerate is the main allosteric effector of hemoglobin, shifting the equilibrium between the oxy and deoxy conformations of hemoglobin preferentially stabilizing the unliganded form. 2,3-Diphosphoglycerate also promotes the polymerization of deoxyhemoglobin in sickle cell disease

Glycerated hemoglobin, alpha 2A beta 2(82) (EF6) N epsilon-glyceryllysine. A new post-translational modification occurring in erythrocyte bisphosphoglyceromutase deficiency.

NO may suppress 2,3-bisphospho-D-glycerate production by (1) inhibiting glyceraldehyde-3-phosphate dehydrogenase, the most critical glycolytic enzyme for the bioavailability of 1,3-bisphosphoglycerate, and to a lesser extent by (2) associated pH changes in the deoxy-hemoglobin-catalyzed depletion of nitrite, a metabolic reservoir of NO
the main activity of the enzyme is synthase (EC 5.4.2.4), converting 1,3-bisphosphoglycerate to 2,3-bisphosphoglycerate. The second activity is mutase (phosphoglycerate mutase, EC 5.4.2.1), catalyzing the interconversion between 2-phosphoglycerate and 3-phosphoglycerate. The third activity is phosphatase (S-succinylglutathione hydrolase, EC 3.1.3.13), hydrolyzing 2,3-bisphosphoglycerate to 3-phosphoglycerate or 2-phosphoglycerate and phosphate
bisphosphoglycerate mutase is a multi-activity enzyme. Its main function is to synthesize the 2,3-bisphosphoglycerate, the allosteric effector of hemoglobin, the enzyme regulates 2,3-bisphosphoglycerate levels, quantum mechanics/molecular mechanics simulations based on the metadynamics and umbrella sampling simulations, detailed overview
the enzyme is responsible for biosynthesis of 2,3-bisphospho-D-glycerate, which is an enhancer of oxygen off-loading from hemoglobin. It is very sensitive to changes in glycolytic rates because its synthesis by BPG synthase is dependent on the availability of the glycolytic intermediate 1,3-bisphosphoglycerate, metabolic enzyme regulation, overview
