ID 1.1.1.281 DE GDP-4-dehydro-6-deoxy-D-mannose reductase. AN GDP-4-keto-6-deoxy-D-mannose reductase. AN GDP-6-deoxy-D-lyxo-4-hexulose reductase. CA GDP-6-deoxy-D-mannose + NAD(P)(+) = GDP-4-dehydro-6-deoxy-D-mannose + CA NAD(P)H. CC -!- Differs from EC 1.1.1.187 in that the only product formed is GDP-D- CC rhamnose (GDP-6-deoxy-D-mannose). CC -!- D-rhamnose is a constituent of lipopolysaccharides of Gram-negative CC plant and human pathogenic bacteria. //
