ID 4.2.1.47 DE GDP-mannose 4,6-dehydratase. AN GDP-D-mannose 4,6-dehydratase. AN GDP-D-mannose dehydratase. AN guanosine 5'-diphosphate-D-mannose oxidoreductase. AN guanosine diphosphomannose 4,6-dehydratase. AN guanosine diphosphomannose oxidoreductase. CA GDP-alpha-D-mannose = GDP-4-dehydro-alpha-D-rhamnose + H2O. CC -!- Forms the first step in the biosynthesis of GDP-alpha-D-rhamnose and CC GDP-alpha-L-fucose. CC -!- In Aneurinibacillus thermoaerophilus L420-91T, this enzyme acts as a CC bifunctional enzyme, catalyzing the above reaction as well as the CC reaction catalyzed by EC 1.1.1.281.
