Carr JF, Gregory ST, Dahlberg AE: Severity of the streptomycin resistance and streptomycin dependence phenotypes of ribosomal protein S12 of Thermus thermophilus depends on the identity of highly conserved amino acid residues. Mol Microbiol. 2007 Feb;63(4):1096-106. The structural basis for the streptomycin dependence phenotype of ribosomal protein S12 mutants is poorly understood. Here we describe the application of site-directed mutagenesis and gene replacement of Thermus thermophilus rpsL to assess the importance of side chain identity and tertiary interactions as phenotypic determinants of drug-dependent mutants. |
