DE   GDP-4-dehydro-D-rhamnose reductase.
AN   GDP-4-keto-6-deoxy-D-mannose reductase.
AN   GDP-4-keto-D-rhamnose reductase.
AN   guanosine diphosphate-4-keto-D-rhamnose reductase.
CA   (1) GDP-alpha-D-rhamnose + NAD(+) = GDP-4-dehydro-alpha-D-rhamnose + NADH
CA   + H(+).
CA   (2) GDP-alpha-D-rhamnose + NADP(+) = GDP-4-dehydro-alpha-D-rhamnose +
CA   NADPH + H(+).
CA   (3) GDP-6-deoxy-alpha-D-talose + NADP(+) = GDP-4-dehydro-alpha-D-rhamnose
CA   + NADPH + H(+).
CA   (4) GDP-6-deoxy-alpha-D-talose + NAD(+) = GDP-4-dehydro-alpha-D-rhamnose
CA   + NADH + H(+).
CC   -!- The enzyme, which operates in the opposite direction to that shown,
CC       forms a mixture of GDP-alpha-D-rhamnose and its C-4 epimer, GDP-6-
CC       deoxy-alpha-D-talose. cf. EC 1.1.1.135 and EC 1.1.1.281.
