oxidoreductase activity, acting on the CH-OH group of donors, NAD or NADP as acceptor GDP-4-dehydro-6-deoxy-D-mannose reductase activity https://github.com/geneontology/go-ontology/issues/28176 https://github.com/geneontology/go-ontology/issues/30193 molecular_function GO:0033705 Note that this enzyme differs from EC:1.1.1.187, GDP-4-dehydro-D-rhamnose reductase, in that the only product formed is GDP-D-rhamnose (GDP-6-deoxy-D-mannose). GDP-4-keto-6-deoxy-D-mannose reductase activity EC:1.1.1.281 GDP-6-deoxy-D-lyxo-4-hexulose reductase activity GDP-6-deoxy-D-mannose:NAD(P)+ 4-oxidoreductase (D-rhamnose-forming) activity Catalysis of the reaction: GDP-6-deoxy-D-mannose + NAD(P)+ = GDP-4-dehydro-6-deoxy-D-mannose + NAD(P)H + H+.
