Enzyme Information

5.1.3.13
dTDP-4-dehydrorhamnose 3,5-epimerase.
based on mapping to UniProt Q9LQ04
dTDP-4-dehydro-6-deoxy-alpha-D-glucose = dTDP-4-dehydro-beta-L-rhamnose.
-!- Occurs in a complex with EC 1.1.1.133.
1.1.1.133
dTDP-4-dehydrorhamnose reductase.
based on mapping to UniProt Q9LQ04
dTDP-beta-L-rhamnose + NADP(+) = dTDP-4-dehydro-beta-L-rhamnose + NADPH.
-!- 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 catalyzes epimerization at C-3 and C-5; the complex has been referred to as dTDP-L-rhamnose synthase.
