ABSTRACT:
A novel method of selecting Streptomyces recombinant DNA-containing host cells and vectors useful in exemplifying the method are described. The vectors confer apramycin resistance to sensitive Streptomyces host cells and thus provide a convenient method of selecting Streptomyces transformants. The apramycin resistance-conferring gene used in the method is an acetyltransferase aac(3)IV gene and can be isolated from E. coli K12 BE1041/pKC309 (NRRL B-15827) on an .about.1.5 kb PstI-EcoRI restriction fragment.
