IntEnz Enzyme Nomenclature


Accepted name:
dTDP-4-dehydrorhamnose reductase
Other names:
TDP-4-keto-rhamnose reductase
dTDP-4-keto-L-rhamnose reductase
dTDP-4-ketorhamnose reductase
thymidine diphospho-4-ketorhamnose reductase
dTDP-6-deoxy-L-mannose dehydrogenase
dTDP-6-deoxy-L-mannose:NADP+ 4-oxidoreductase
dTDP-6-deoxy-β-L-mannose:NADP+ 4-oxidoreductase
Systematic name:
dTDP-β-L-rhamnose:NADP+ 4-oxidoreductase



In the reverse direction, reduction on the 4-position of the hexose moiety takes place only while the substrate is bound to another enzyme that catalyses epimerization at C-3 and C-5; the complex has been referred to as dTDP-L-rhamnose synthase.
