The stereospecificity of the enzyme-dependent oxidation of alpha-[4R-2H]NADH has been determined for four dehydrogenases: two pro-R specific enzymes, pig heart malate dehydrogenase and yeast alcohol dehydrogenase; and two pro-S specific enzymes, rabbit muscle glycerol-3-phosphate dehydrogenase and Rhodopseudomonas spheroides 3-hydroxybutyrate dehydrogenase. In all cases, an enzyme-dependent and substrate-specific oxidation to alpha-NAD+ is observed with the stereochemistry of oxidation identical with that found for the oxidation of the correspondingly labeled beta-NADH. The ability of dehydrogenases from diverse sources to utilize alpha-NADH in a stereochemically competent fashion is discussed in relation to proposed interactions between the nicotinamide sugar moiety and active site residues or obligatory alignments of the pyridine and sugar moieties.
