GDP-mannose 4,6-dehydratase.
based on mapping to UniProt P0AC88
GDP-alpha-D-mannose = GDP-4-dehydro-alpha-D-rhamnose + H(2)O.
-!- Forms the first step in the biosynthesis of GDP-alpha-D-rhamnose and GDP-alpha-L-fucose. -!- In Aneurinibacillus thermoaerophilus L420-91T, this enzyme acts as a bifunctional enzyme, catalyzing the above reaction as well as the reaction catalyzed by EC 1.1.1.281.
