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. The FMN riboswitch (also known as RFN element) is a highly conserved RNA element which is naturally occurring, and is found frequently in the 5'-untranslated regions of prokaryotic mRNAs that encode for flavin mononucleotide (FMN) biosynthesis and transport proteins. … See more The function of the FMN riboswitch is twofold; first, riboswitches contain an aptamer component, which allows this RNA molecule to bind to its target molecule, FMN, resulting in a series of conformational changes See more While riboswitches are not present in mammalian eukaryotic cells, they are present in prokaryotic cells, thus making them possible targets for antibiotic drug development. … See more • Page for FMN riboswitch (RFN element) at Rfam See more
WebOct 1, 2010 · The FMN riboswitch. Roseoflavin, which is a natural pigment isolated from Streptomyces davawenensis, exhibits an antimicrobial activity involved in the inhibition of riboflavin biosynthesis [45]. Roseoflavin might potentially target the FMN riboswitch because of its structural similarity to flavin mononucleotide (FMN) [46, 47]. WebFMN riboswitches are genetic elements that, in many bacteria, control genes responsible for biosynthesis and/or transport of riboflavin (vitamin B2 ). We report that the …
