CC -!- FUNCTION: Catalyzes the oxidative phosphorylation of glyceraldehyde 3-
CC phosphate (G3P) to 1,3-bisphosphoglycerate (BPG) using the cofactor
CC NAD. The first reaction step involves the formation of a hemiacetal
CC intermediate between G3P and a cysteine residue, and this hemiacetal
CC intermediate is then oxidized to a thioester, with concomitant
CC reduction of NAD to NADH. The reduced NADH is then exchanged with the
CC second NAD, and the thioester is attacked by a nucleophilic inorganic
CC phosphate to produce BPG. {ECO:0000256|ARBA:ARBA00003501}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-glyceraldehyde 3-phosphate + NAD(+) + phosphate = (2R)-3-
CC phospho-glyceroyl phosphate + H(+) + NADH; Xref=Rhea:RHEA:10300,

CC -!- SUBUNIT: Homotetramer. {ECO:0000256|ARBA:ARBA00011881}.
CC -!- SIMILARITY: Belongs to the glyceraldehyde-3-phosphate dehydrogenase
CC family. {ECO:0000256|ARBA:ARBA00007406, ECO:0000256|RuleBase:RU000397}.
