RL Submitted (JUN-2007) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the two-step NADP-dependent conversion of GDP-4-
CC dehydro-6-deoxy-D-mannose to GDP-fucose, involving an epimerase and a
CC reductase reaction. {ECO:0000256|HAMAP-Rule:MF_00956}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=GDP-beta-L-fucose + NADP(+) = GDP-4-dehydro-alpha-D-rhamnose +
CC H(+) + NADPH; Xref=Rhea:RHEA:18885, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:57273, ChEBI:CHEBI:57783, ChEBI:CHEBI:57964,
CC ChEBI:CHEBI:58349; EC=1.1.1.271; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_00956};
CC -!- PATHWAY: Nucleotide-sugar biosynthesis; GDP-L-fucose biosynthesis via
CC de novo pathway; GDP-L-fucose from GDP-alpha-D-mannose: step 2/2.
CC {ECO:0000256|HAMAP-Rule:MF_00956}.
CC -!- SIMILARITY: Belongs to the NAD(P)-dependent epimerase/dehydratase
CC family. Fucose synthase subfamily. {ECO:0000256|ARBA:ARBA00005959,
CC ECO:0000256|HAMAP-Rule:MF_00956}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
