IntEnz Enzyme Nomenclature


Accepted name:
GDP-4-dehydro-6-deoxy-D-mannose reductase
Other names:
GDP-4-keto-6-deoxy-D-mannose reductase [ambiguous]
GDP-6-deoxy-D-lyxo-4-hexulose reductase
GDP-6-deoxy-D-mannose:NAD(P)+ 4-oxidoreductase (D-rhamnose-forming)
Systematic name:
GDP-α-D-rhamnose:NAD(P)+ 4-oxidoreductase (D-rhamnose-forming)



This enzyme differs from EC, GDP-4-dehydro-D-rhamnose reductase, in that the only product formed is GDP-α-D-rhamnose (GDP-6-deoxy-α-D-mannose). D-Rhamnose is a constituent of lipopolysaccharides of Gram-negative plant and human pathogenic bacteria.
