CC -!- FUNCTION: Catalyzes the conversion of GDP-D-mannose to GDP-4-dehydro-6-
CC deoxy-D-mannose. {ECO:0000255|HAMAP-Rule:MF_00955}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=GDP-alpha-D-mannose = GDP-4-dehydro-alpha-D-rhamnose + H2O;
CC Xref=Rhea:RHEA:23820, ChEBI:CHEBI:15377, ChEBI:CHEBI:57527,
CC ChEBI:CHEBI:57964; EC=4.2.1.47; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00955};
CC -!- COFACTOR:
CC Name=NADP(+); Xref=ChEBI:CHEBI:58349;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00955};
CC -!- PATHWAY: Nucleotide-sugar biosynthesis; GDP-L-fucose biosynthesis via
CC de novo pathway; GDP-L-fucose from GDP-alpha-D-mannose: step 1/2.
CC -!- SIMILARITY: Belongs to the NAD(P)-dependent epimerase/dehydratase
CC family. GDP-mannose 4,6-dehydratase subfamily. {ECO:0000255|HAMAP-
CC Rule:MF_00955}.
