Functioni

Involved in the gluconeogenesis. Catalyzes the oxidative phosphorylation of glyceraldehyde 3-phosphate (G3P) to 1,3-bisphosphoglycerate (BPG) using the cofactor NADP. The first reaction step involves the formation of a hemiacetal intermediate between G3P and a cysteine residue, and this hemiacetal intermediate is then oxidized to a thioester, with concomitant reduction of NADP to NADPH. The reduced NADPH is then exchanged with the second NADP, and the thioester is attacked by a nucleophilic inorganic phosphate to produce BPG.1 Publication

Catalytic activityi

D-glyceraldehyde 3-phosphate + phosphate + NAD(P)+ = 3-phospho-D-glyceroyl phosphate + NAD(P)H.1 Publication

Kineticsi

Kcat is 1 sec(-1) for dehydrogenase activity with NAD (at pH 9.2 and 25 degrees Celsius). Kcat is 8 sec(-1) for dehydrogenase activity with NADP (at pH 9.2 and 25 degrees Celsius).1 Publication
