Structural basis for control of bacterial RNA polymerase pausing by a riboswitch and its ligand
{{output}}
Folding of nascent transcripts can be modulated by the RNA polymerase (RNAP) that carries out their transcription, and vice versa. A pause of RNAP during transcription of a preQ1 riboswitch (termed que-PEC) is stabilized by a previously characterized template ... ...
