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
ε-rhodomycinone = methyl (1R,2R,4S)-2-ethyl-2,4,5,7,12-pentahydroxy-6,11-dioxo-1,2,3,4,6,11-hexahydrotetracene-1-carboxylate

Other name(s):

DnrF; RdmE; aklavinone 11-hydroxylase (incorrect)

Systematic name:

aklavinone,NADPH:oxygen oxidoreductase (12-hydroxylating)

Comments:

The enzymes from the Gram-positive bacteria Streptomyces peucetius and Streptomyces purpurascens participate in the biosynthesis of daunorubicin, doxorubicin and rhodomycins. The enzyme from Streptomyces purpurascens is an FAD monooxygenase.
