dTDP-glucose 4,6-dehydratase  M-CSA #228

The conversion of dTDP-glucose into dTDP-4-keto-6-deoxyglucose by Escherichia coli dTDP-glucose 4,6-dehydratase) takes place in the active site in three steps: dehydrogenation to dTDP-4-ketoglucose, dehydration to dTDP-4-ketoglucose-5,6-ene, and rereduction of C6 to the methyl group. The 4,6-dehydratase makes use of tightly bound NAD+ as the coenzyme for transiently oxidizing the substrate, activating it for the dehydration step.
