WebApr 20, 2024 · The FMN riboswitch is located in the 5′-UTR of polycistronic mRNA encodes five proteins responsible for FMN biosynthesis in many bacteria. (A) In the absence of FMN, the riboswitch aptamer folds into a structure that allows the formation of an antiterminator and, at the same time, excludes the formation of the terminator. WebWe have solved the crystal structures of the metabolite-sensing domain of the F. nucleatum riboswitch bound to FMN, riboflavin, and antibiotic roseoflavin (Serganov et al. 2009). The structure of the FMN riboswitch, centered on an FMN-bound six-stem junction adopts a butterfly-like scaffold, stapled together by opposingly directed but nearly ...
