Catalyzes the oxidative phosphorylation of glyceraldehyde 3-phosphate (G3P) to 1,3-bisphosphoglycerate (BPG) using the cofactor NAD. D-glyceraldehyde 3-phosphate + NAD(+) + phosphate = (2R)-3-phospho-glyceroyl phosphate + H(+) + NADH Carbohydrate degradation; glycolysis; pyruvate from D-glyceraldehyde 3-phosphate: step 1/5. Homotetramer. Expression shows a diurnal pattern of oscillation across the 24-hour light-dark, with increased levels during the dark period (at protein level) (Ref.2). Up-regulated in the early and late stationary growth phases as compared to the exponential growth phase (PubMed:23291769). Belongs to the glyceraldehyde-3-phosphate dehydrogenase family.
