In conjunction with genomic data our structure suggests that the SAM/SAH-riboswitches might be an evolutionary late invention and not a remnant of a primordial RNA-world as suggested for other riboswitches.

Webb12 dec. 2024 · Riboswitches are natural biosensors that can regulate gene expression by sensing small molecules. Knowledge of the structural dynamics of riboswitches is crucial to elucidate their regulatory mechanism and develop RNA biosensors. Webb5 aug. 2024 · Riboswitches are gene control elements that directly bind to specific ligands to regulate gene expression without the need for proteins. They are found in all three domains of life, including Bacteria, Archaea, and Eukaryota. Riboswitches are mostly spread in bacteria and archaea.

WebbRiboswitches are regions of mRNAs that contain specific evolutionarily conserved ligand-binding (sensor) domains along with a variable sequence, termed the expression platform, that enables regulation of the downstream coding sequences. The term “riboswitch” reflects the ability of these noncoding RNAs to function as genetic switches.
