EC 1.1.1.133     
Accepted name: dTDP-4-dehydrorhamnose reductase

Glossary: dTDP-4-dehydro-β-L-rhamnose = dTDP-4-dehydro-6-deoxy-β-L-mannose
dTDP-4-β-L-rhamnose = dTDP-6-deoxy-β-L-mannose
Other name(s): dTDP-4-keto-L-rhamnose reductase; dTDP-4-ketorhamnose reductase; TDP-4-keto-rhamnose reductase; thymidine diphospho-4-ketorhamnose reductase; 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
Comments: 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.
