ID 1.1.1.134 DE dTDP-6-deoxy-L-talose 4-dehydrogenase. CA dTDP-6-deoxy-beta-L-talose + NADP(+) = dTDP-4-dehydro-beta-L-rhamnose + CA H(+) + NADPH. CC -!- Oxidation on the 4-position of the hexose moiety takes place only CC while the substrate is bound to another enzyme that catalyzes CC epimerization at C-3 and C-5. //
