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:0000269|PubMed:6822480}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=D-glyceraldehyde 3-phosphate + NAD(+) + phosphate = (2R)-3-
CC         phospho-glyceroyl phosphate + H(+) + NADH; Xref=Rhea:RHEA:10300,

CC         Evidence={ECO:0000269|PubMed:6822480};
CC   -!- ACTIVITY REGULATION: Inhibited by pentalenolactone (PL).
CC       {ECO:0000269|PubMed:6822480}.
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       Kinetic parameters:
CC         KM=110 uM for NAD (at pH 8 and 26 degrees Celsius)
CC         {ECO:0000269|PubMed:6822480};
CC         KM=250 uM for G3P (at pH 8 and 26 degrees Celsius)
CC         {ECO:0000269|PubMed:6822480};
CC   -!- PATHWAY: Carbohydrate degradation; glycolysis; pyruvate from D-
CC       glyceraldehyde 3-phosphate: step 1/5. {ECO:0000305}.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000269|PubMed:6822480}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- INDUCTION: In the absence of pentalenolactone (PL).
CC       {ECO:0000269|PubMed:6822480}.
CC   -!- SIMILARITY: Belongs to the glyceraldehyde-3-phosphate dehydrogenase
CC       family. {ECO:0000305}.
