Abstract excerpt
Three ribosomal RNA mutations conferring resistance to the antibiotic kasugamycin were isolated using a strain of Escherichia coli in which all of the rRNA is transcribed from a plasmid-encoded rrn operon. The mutations, A794G, G926A, and A1519C, mapped to universally conserved sites in the 16 S RNA gene. Site-directed mutagenesis studies showed that virtually all mutations at these three sites conferred...
