Abstract Widespread manganese-sensing transcriptional riboswitches effect the dependable gene regulation needed for bacterial manganese homeostasis in changing environments. Riboswitches – like most structured RNAs – are believed to fold co-trans

RNA interference (RNAi) is a set of intracellular pathways in eukaryotes that controls both exogenous and endogenous gene expression. The power of RNAi to knock down (silence) any gene of interest by the introduction of synthetic small-interfering (s

Due to the energetic frustration of RNA folding, tertiary structured RNA is typically characterized by a rugged folding free energy landscape where deep kinetic barriers separate numerous misfolded states from one or more native states. While most in

A single molecule fluorescence study revealed three dynamically interconverting conformations of the fluoride riboswitch from Bacillus cereus, where an anionic ligand snap-locks a docked conformation through a long-range interaction necessary for dow

Cellular biomolecular condensates, termed ribonucleoprotein (RNP) granules, are often enriched in messenger RNA (mRNA) molecules relative to the surrounding cytoplasm. Yet, the spatial localization and diffusion of mRNAs in close proximity to phase s

Traces from single-molecule fluorescence microscopy (SMFM) experiments exhibit photophysical artifacts that typically make analysis time-consuming. Here, the authors have developed an easily accessible software, AutoSiM, for two distinct applications

Riboswitches bind intracellular metabolites and control bacterial gene expression. Here, by using X-ray crystallography, molecular dynamics simulations, and single-molecule fluorescence resonance energy transfer, the authors show how a local Mn2+ ion

Transcriptional riboswitches involve RNA aptamers that are typically found in the 5′ untranslated regions (UTRs) of bacterial mRNAs and form alternative secondary structures upon binding to cognate ligands. Alteration of the riboswitch's secondary

Riboswitches on 5′ ends of mRNAs are important for bacterial gene regulation. Here the authors probe the mechanism of a tRNA aminoacylation sensing T-box riboswitch using single-molecule fluorescence microscopy to characterize dynamic solution conf

Noncoding, structured 5′-untranslated regions (5′-UTRs) of bacterial messenger RNAs (mRNAs) can control translation efficiency by forming structures that either recruit or repel the ribosome. Here we exploit a 5′-UTR embedded preQ1-sensing, pse
