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.
Genes controlled by S-box element:
- cysH-cysP-sat-cysC-ylnD-ylnE-ylnF
- metE
- metK
- yitJ-yitI-yitH
- metI-metC
- mtnK-mtnS
- ykrW
- yoaD
- yusC
- yxjG
- yxjH
