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:0000250|UniProtKB:P0A9B2}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-glyceraldehyde 3-phosphate + NAD(+) + phosphate = (2R)-3-
CC phospho-glyceroyl phosphate + H(+) + NADH; Xref=Rhea:RHEA:10300,

CC ChEBI:CHEBI:57604, ChEBI:CHEBI:57945, ChEBI:CHEBI:59776; EC=1.2.1.12;
CC Evidence={ECO:0000250|UniProtKB:P0A9B2};
CC -!- PATHWAY: Carbohydrate degradation; glycolysis; pyruvate from D-
CC glyceraldehyde 3-phosphate: step 1/5. {ECO:0000305}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000250|UniProtKB:P0A9B2}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the glyceraldehyde-3-phosphate dehydrogenase
CC family. {ECO:0000305}.
