genes for the biosynthesis of daunorubicin ( daunomycin ) and doxorubicin ( adriamycin ) , important antitumor drugs , were cloned from streptomyces peucetius ( the daunorubicin producer ) and s. peucetius subsp . caesius ( the doxorubicin producer ) by use of the acti/tcmia and actiii polyketide synthase gene probes .
