Accepted name:
13-deoxydaunorubicin hydroxylase
Other name:
Systematic name:
13-deoxydaunorubicin,NADPH:oxygen oxidoreductase (13-hydroxylating)



The enzymes from the Gram-positive bacteria Streptomyces sp. C5 and Streptomyces peucetius show broad substrate specificity for structures based on an anthracycline aglycone, but have a strong preference for 4-methoxy anthracycline intermediates (13-deoxydaunorubicin and 13-dihydrodaunorubicin) over their 4-hydroxy analogues (13-deoxycarminomycin and 13-dihydrocarminomycin), as well as a preference for substrates hydroxylated at the C-13 rather than the C-14 position.
