The S-box element is a riboswitch that controls different genes of sulphur metabolism in response to the presence of S-adenosylmethionine.

  • Upon binding of SAM, the riboswitch adopts a terminator structure resulting in transcription termination.
  • In the absence of SAM, the riboswitch has the antitermination structure that allows transcription elongation into the controlled gene/ operon.
  • S-box riboswitch turnover is initiated by RNase Y PubMed
