Effects of mutations to streptomycin resistance on the rate of translation of mutant genetic information.

abstract：:The transduction efficiency of Tn551, a staphylococcal transposon coding for erythromycin resistance (ermB), was increased by a factor of about five in acceptor strains carrying the gene for methicillin resistance (mec), as compared with methicillin-sensitive strains. This enhancement was independent of the generalize...
