    The stereochemical course of the dTDP-glucose oxidoreductase (EC 4.2.1.46) reaction was studied using enzyme partially purified from Escherichia coli and dTDP-(6R)- and (6S)-[4-2H, 6-3H]glucose as substrate. The latter was prepared enzymatically by reduction of (3R)- and (3S)-3-P-[3-3H]glycerate to the 1-deuterated 3-P-glyceraldehyde with (4S)-[4-2H]NADH, followed first by conversion to glucose-1-P with the glycolytic enzymes, and then by transformation into the dTDP derivative. The stereospecifically labeled dTDP-glucose samples were mixed with nonlabeled carrier material and converted to dTDP-4-keto-6-deoxyglucose, which contained a chiral methyl group as shown by chirality analysis of the acetic acid resulting from Kuhn-Roth oxidation of the sugar nucleotide. These results confirm that the hydrogen transfer from C4 to C6 is intramolecular and show that the migrating hydrogen replaces the 6-hydroxyl group with inversion of configuration. Assuming that the hydrogen transfer, since it is intramolecular, must be suprafacial, it follows that the elimination of water from C5 and C6 is formally syn, whereas the reduction of the resulting delta5,6-double bond formally involves an anti addition of H+ and H-.
