bisphosphoglycerate mutase activity
Definition
Target type: molecularfunction
Catalysis of the reaction: 3-phospho-D-glyceroyl phosphate = 2,3-bisphospho-D-glycerate. [EC:5.4.2.4]
Bisphosphoglycerate mutase activity catalyzes the reversible interconversion of 1,3-bisphosphoglycerate (1,3-BPG) and 2,3-bisphosphoglycerate (2,3-BPG). This reaction is essential in red blood cells for regulating the oxygen affinity of hemoglobin. 1,3-BPG is a substrate in the glycolytic pathway, while 2,3-BPG is an allosteric effector of hemoglobin. The enzyme utilizes a phosphoryl transfer reaction mechanism, where the phosphate group from 1,3-BPG is temporarily transferred to an active site histidine residue before being transferred to the 2-position of the glycerate molecule. This reaction involves a conformational change in the enzyme, which facilitates the transfer of the phosphate group. The enzyme has a strict requirement for divalent metal ions such as Mg2+ or Mn2+, which are involved in stabilizing the transition state and facilitating the phosphoryl transfer. The activity of bisphosphoglycerate mutase is regulated by factors such as pH, temperature, and the concentration of substrates and products. Additionally, the enzyme is subject to post-translational modifications such as phosphorylation, which can affect its activity. In red blood cells, the activity of this enzyme is tightly controlled to maintain the appropriate levels of 2,3-BPG, which is crucial for oxygen delivery to tissues.'
