WebJun 1, 2004 · Riboswitches are complex folded RNA domains that serve as receptors for specific metabolites. These domains are found in the non-coding portions of various mRNAs, where they control gene expression... WebApr 7, 2024 · In this context, the functional consensus for Cbl and FMN riboswitch TLs is YGNRA (wherein 80% of sequences are UGNAA, and UGHAA is functionally favored). Notably, this experimentally defined consensus is distinct from the tRNA TL, which uses U at position 2 ( Fig. 1 a ) rather than G — a finding that has implications for TL classification …
Affinity-Based Profiling of the Flavin Mononucleotide Riboswitch
WebOct 22, 2015 · Flavin mononucleotide (FMN) riboswitches are genetic elements, which in many bacteria control genes responsible for biosynthesis and/or transport of riboflavin ( rib genes). Cytoplasmic riboflavin is rapidly … 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 crypto hash javascript
