Glossary:

aklavinone = methyl (1R,2R,4S)-2-ethyl-2,4,5,7-tetrahydroxy-6,11-dioxo-1,2,3,4,6,11-hexahydrotetracene-1-carboxylate
aklaviketone = methyl (1R,2R)-2-ethyl-2,5,7-trihydroxy-4,6,11-trioxo-1,2,3,4,6,11-hexahydrotetracene-1-carboxylate

Other name(s):

dauE (gene name); aknU (gene name)

Systematic name:

aklavinone:NADP⁺ oxidoreductase

Comments:

The enzyme is involved in the synthesis of the aklavinone aglycone, a common precursor for several anthracycline antibiotics including aclacinomycins, daunorubicin and doxorubicin. The enzyme from the Gram-negative bacterium Streptomyces sp. C5 produces daunomycin.
