Transcriptional riboswitches involve RNA aptamers that are typically found in the 5′
untranslated regions (UTRs) of bacterial mRNAs and form alternative secondary structures …

The International Society of RNA Nanotechnology and Nanomedicine (ISRNN) hosts an
annual meeting series focused on presenting the latest research achievements involving …

T-box riboswitches are multi-domain noncoding RNAs that surveil individual amino acid
availabilities in most Gram-positive bacteria. T-boxes directly bind specific tRNAs, query …

Biological motors are highly complex protein assemblies that generate linear or rotary
motion, powered by chemical energy. Synthetic motors based on DNA nanostructures, bio …

Cotranscriptional RNA folding is crucial for the timely control of biological processes, but
because of its transient nature, its study has remained challenging. While single-molecule …

Bacterial riboswitches couple small-molecule ligand binding to RNA conformational
changes that widely regulate gene expression, rendering them potential targets for antibiotic …

Cotranscriptional RNA folding is widely assumed to influence the timely control of gene
expression, but our understanding remains limited. In bacteria, the fluoride (F−)-sensing …

PreQ1-III riboswitches are newly identified RNA elements that control bacterial genes in
response to preQ1 (7-aminomethyl-7-deazaguanine), a precursor to the essential …

ABSTRACT RNA is a versatile biomolecule capable of transferring information, taking on
distinct three-dimensional shapes, and reacting to ambient conditions. RNA molecules …

In Gram-positive bacteria, T-box riboswitches control gene expression to maintain the
cellular pools of aminoacylated tRNAs essential for protein biosynthesis. Co-transcriptional …
