mechanism: after the active site His-8 is phosphorylated by the cofactor 2,3-diphosphoglycerate a substrate molecule binds. Subsequently a phospho-transfer takes place via a ping-pong-mechanism. After release of the product the enzyme remains phosphorylated and catalytically competent
-
2-phospho-D-glycerate = 3-phospho-D-glycerate
ping-pong mechanism via a phosphorylated His-intermediate
-
2-phospho-D-glycerate = 3-phospho-D-glycerate
ping-pong mechanism via a phosphorylated His-intermediate
-
2-phospho-D-glycerate = 3-phospho-D-glycerate
ping-pong or phosphoenzyme mechanism
-
2-phospho-D-glycerate = 3-phospho-D-glycerate
mechanism of BPGM begins with an unphosphorylated enzyme, the active site histidine of which performs a nucleophilic SN2 attack on the 1,3-bisphosphoglycerate substrate to produce phosphohistidine and 3-phosphoglycerate. The 2'-hydroxyl group then performs a second nucleophilic attack that transfers the phosphate from the active site histidine to the substrate, forming 2,3-bisphosphoglycerate
