ENZYME entry: EC 1.14.13.181

PURL: https://purl.expasy.org/enzyme/EC/1.14.13.181
Accepted Name
13-deoxydaunorubicin hydroxylase
Reaction catalysed
  • 13-deoxydaunorubicin + NADPH + O2 + H(+) = 13-dihydrodaunorubicin + NADP(+) + H2O
  • 13-dihydrodaunorubicin + NADPH + O2 + H(+) = daunorubicin + NADP(+) + 2 H2O
Comment(s)
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 analogs (13-deoxycarminomycin and 13-dihydrocarminomycin), as well as a preference for substrates hydroxylated at the C-13 rather than the C-14 position.
