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]. WebMar 19, 2012 · Indeed, the FMN-sensing riboswitch from the Gram-positive bacterium Bacillus subtilis controls expression of riboflavin biosynthetic genes via early intrinsic termination of transcription (20, 21), whereas FMN riboswitches in E. coli and other Gram-negative bacteria were postulated to work primarily via translational repression . sicilian wedding cookies
