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 aabsence of SAM, the riboswitch has the antitermination structure that allows transcription elongation into the controlled gene/ operon.
