LITERATURE
in response to capreomycin, cells downregulate TlyA-mediated methylation of 16S and 23S (cf. EC 2.1.1.226) rRNA resulting in decreased drug susceptibility. Incubation with capreomycin during bacterial growth results in a reduced post-transcriptional modification of rRNA at TlyA-dependent sites (1409 in 16S and 1920 in 23S)
the common resistance mutation A1408G is accompanied by a physiological change that involves increased expression of the tlyA gene
