Generation of orthogonally selective bacterial riboswitches by targeted mutagenesis and in vivo screening.

Abstract excerpt

Riboswitches are naturally occurring RNA-based genetic switches that control gene expression in response to the binding of small-molecule ligands, typically through modulation of transcription or translation. Their simple mechanism of action and the expanding diversity of riboswitch classes make them attractive targets for the development of novel gene expression tools. The essential first step in realizing this...
