Doxorubicin (DXN) and daunorubicin (DNR) are anthracycline-type antitumor drugs. The glycosyltransferase dnrS responsible for glycosylation of DXN aglycone was disrupted from Streptomyces peucetius ATCC 27952. The mutant strain complementation with glycosyltransferases from Streptomyces galilaeus (aknS/aknT) and dimethyltransferase (desVI) from Streptomyces venezuelae caused modification in ε-rhodomycinone by transferring TDP-rhodosamine to produce an Epelmycin-D. A methyltransferase (dnrK) in S. peucetius changed that compound to 7-O-L-rhodosaminyl-4-O-methyl-e-rhodomycinone. The products were confirmed by high performance liquid chromatography-photodiode array (HPLC-PDA) and high resolution liquid chromatography-electrospray ionization-quadrupole-time of flight-mass spectrometry (HRLC-ESI-QTOF -MS) analyses.
