Collection of regulogs for FMN (RF00050) RNA regulatory element

The FMN riboswitch, also known as RFN element, is a highly conserved RNA structure that is involved in regulation of riboflavin metabolism in Bacteria. This element is a metabolite-dependent riboswitch that directly binds FMN in the absence of proteins and regulates gene expression via either transcriptional or translational attenuation mechanisms [12456892, 12464185]. Riboflavin (vitamin B2) is an essential component of the basic metabolism, being a precursor of coenzymes flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN). The FMN-dependent repression of the riboflavin operon of Bacillus subtilis was shown to involve premature termination of transcription, and to be abolished by mutations in this region [18666549]. more
