DTDP 6 deoxy L talose 4 dehydrogenase (NAD )

DTDP-6-deoxy-L-talose 4-dehydrogenase (NAD⁺) (EC 1.1.1.339, tll (gene name)) is an enzyme with systematic name dTDP-6-deoxy-beta-L-talose:NAD⁺ 4-oxidoreductase. This enzyme catalyses the following chemical reaction

dTDP-6-deoxy-beta-L-talose + NAD⁺ ⇌ dTDP-4-dehydro-6-deoxy-beta-L-mannose + NADH + H⁺

The enzyme from bacterium Aggregatibacter actinomycetemcomitans participates in the biosynthesis of the serotype c-specific polysaccharide antigen.
