The Lysine riboswitch is a metabolite binding RNA element found within certain messenger RNAs that serve as a precision sensor for the amino acid lysine. Allosteric rearrangement of mRNA structure is mediated by ligand binding, and this results in modulation of gene expression.[1] This riboswitches is found in a number of genes involved in lysine metabolism, including lysC.[2][3] The lysine riboswitch has also been identified independently and called the L box.[4]
