- Abstract
- The aklavinone 11-hydroxylase gene and two doxorubicin resistance genes cloned from Streptomyces peucetius subsp. caesius ATCC 27952 were introduced into doxorubicin-sensitive Streptomyces galilaeus ATCC 31133, an aclacinomycin producer. The doxorubicin resistance genes drrA and drrB endowed S. galilaeus with high-level resistance to doxurubicin, indicating that the resistance mechanism for doxorubicin might be different from that for aclacinomycin A. Transformation of S. galilaeus ATCC 31133 with plasmid pMC213 containing the aklavinone 11-hydroxylase gene (dnrF) resulted in the production of many red pigments. A new metabolite was purified, and the position of the newly introduced hydroxyl group was determined. This result indicated that the aklavinone 11-hydroxylase gene was stably expressed in S. galilaeus ATCC 31133 and that it gave rise tn a hybrid aclacinomycin A which showed highly specific in vitro cytotoxicity against leukemia and melanoma cell lines.
