摘要
Ribosomal resistance to pactamycin in clones of Streptomyces lividans containing DNA (pct) from Streptomyces pactum, the pactamycin producer, involves methylation of 16S RNA. The modified residue A-941 in S. lividans 16S rRNA (A-964 in the homologous Escherichia coli sequence) is converted to 1-methyladenosine, and the ribosomal ability to bind pactamycin is reduced or abolished.
