| Abstract |
The ribosome has the intrinsic capacity to monitor the sequence and structure of the nascent peptide. This fundamental property of the ribosome is often exploited in regulation of gene expression, in particular, for activation of expression of genes conferring resistance to ribosome-targeting antibiotics. Induction of expression of these genes is controlled by the programmed stalling of the ribosome at a regulatory open reading frame located upstream of the resistance cistron. Formation of the stalled translation complex depends on the presence of an antibiotic in the ribosome exit tunnel and the sequence of the nascent peptide. In this review, we summarize our current understanding of the molecular mechanisms of drug- and nascent peptide-dependent ribosome stalling. |
