Timeline
Description
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. Lysine riboswitch are most abundant in Bacillota and Gammaproteobacteria where they are found upstream of a number of genes involved in lysine biosynthesis, transport and catabolism. The lysine riboswitch has also been identified independently and called the L box (From Wikipedia).Gene association
The pathway of lysine riboswitches regulating lysine synthesis in B. subtilis[2].
Gene regulation
Potential mechanism of translation regulation by lysine riboswitch in B. subtilis (Top) and E. coli (Bottom). RBS denotes ribosome binding site. We present the prototypical mechanism, but not all possible mechanisms[2,3].
