[Kasugamycin methylase modified by ribosomal RNA from group A streptococci].

Kasugamycin sensitivity in Escherichia coli depends on the specific enzyme methylating rRNA. Native group A streptococci (GAS) were found to be sensitive to kasugamycin. After introduction of the erythromycin gene located on the transposon Tn916E into GAS some of the strains obtained kasugamycin resistance together with erythromycin resistance (erm).
