Description
The bacterial enzyme requires bound NAD+. This enzyme forms the first step in the biosynthesis of GDP-α-D-rhamnose and GDP-β-L-fucose. In Aneurinibacillus thermoaerophilus L420-91T, this enzyme acts as a bifunctional enzyme, catalysing the above reaction as well as the reaction catalysed by EC 1.1.1.281, GDP-4-dehydro-6-deoxy-D-mannose reductase. Belongs to the short-chain dehydrogenase/reductase enzyme family, having homologous structures and a conserved catalytic triad of Lys, Tyr and Ser/Thr residues
