the reversible reactions occur by shuttle movements of a hydrogen negative ion from the C3 atom of the substrate to the C4 atom of NAD+ and from the C4 atom of NADH to the C3 atom of the product. The reaction may be further coupled to the withdrawal of a proton from the hydroxyl group of the substrate by the ionized Tyr155 residue
