Riboswitches are highly conserved metabolite binding domains that are present in the 5'-UTR of certain mRNAs in bacteria. These structural elements bind specific metabolites in the aptamer domain that results in allosteric rearrangement in the adjacent expression platform to regulate gene expression associated with biosythesis and transport. In Bacillus subtilis, the 5'-UTR of xpt-pbuX mRNA binds guanine (1) with high precision to down-regulate the expression of genes by forming transcription terminator structures. | Riboswitches are highly conserved metabolite binding domains that are present in the 5'-UTR of certain mRNAs in bacteria.

| This Sandbox is Reserved from September 14, 2021, through May 31, 2022, for use in the class Introduction to Biochemistry taught by User:John Means at the University of Rio Grande, Rio Grande, OH, USA. This reservation includes 5 reserved sandboxes (Sandbox Reserved 1590 through Sandbox Reserved 1594). |
To get started:
More help: Help:Editing. For an example of a student Proteopedia page, please see Photosystem II, Tetanospasmin, or Guanine riboswitch. |
