Ligands: CL, EDO, NAD, PEG, PO4 Activity: Glyceraldehyde-3-phosphate dehydrogenase (phosphorylating), with EC number 1.2.1.12 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [G3P_CHLTR] Catalyzes the oxidative phosphorylation of glyceraldehyde 3-phosphate (G3P) to 1,3-bisphosphoglycerate (BPG) using the cofactor NAD. 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 NAD to NADH. The reduced NADH is then exchanged with the second NAD, and the thioester is attacked by a nucleophilic inorganic phosphate to produce BPG.[UniProtKB:P00362]
