glyceraldehyde-3-phosphate dehydrogenase (NAD+) (phosphorylating) activity
Definition
Target type: molecularfunction
Catalysis of the reaction: D-glyceraldehyde 3-phosphate + phosphate + NAD+ = 3-phospho-D-glyceroyl phosphate + NADH + H+. [EC:1.2.1.12]
Glyceraldehyde-3-phosphate dehydrogenase (NAD+) (phosphorylating) activity catalyzes the reversible oxidation of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate. This reaction is a key step in glycolysis, the central pathway for energy production in living organisms. The enzyme utilizes NAD+ as a coenzyme, which is reduced to NADH during the oxidation of glyceraldehyde-3-phosphate. The reaction also involves the phosphorylation of glyceraldehyde-3-phosphate by inorganic phosphate, resulting in the formation of 1,3-bisphosphoglycerate. This step is essential for the generation of ATP in glycolysis, as the high-energy phosphate bond in 1,3-bisphosphoglycerate can be transferred to ADP to produce ATP. The active site of glyceraldehyde-3-phosphate dehydrogenase contains a cysteine residue that forms a covalent thiohemiacetal intermediate with glyceraldehyde-3-phosphate during the catalytic process. This intermediate is then oxidized by NAD+, leading to the formation of 1,3-bisphosphoglycerate and the reduction of NAD+ to NADH.'
