Riboswitches as hormone receptors: hypothetical cytokinin-binding riboswitches in Arabidopsis thaliana [PDF]
Biology Direct, 2010 Riboswitches are mRNA elements that change conformation when bound to small molecules. They are known to be key regulators of biosynthetic pathways in both prokaryotes and eukaryotes.The hypothesis presented here is that riboswitches function as receptors in hormone perception.

Virulence, 2020 The proliferation of antibiotic resistance has its origins in horizontal gene transfer. The class 1 integrons mediate gene transfer by assimilating antibiotic-resistance genes through site-specific recombination.

CIA5 and its interacting metal‐binding GTPase ZNG3 are degraded by the proteasome in Zn deficiency
The Plant Journal, Volume 127, Issue 1, July 2026.SUMMARY Carbon and zinc (Zn) metabolism are tightly connected in phototrophs, as carbonic anhydrases critical for CO2 assimilation are highly abundant Zn enzymes. The eukaryotic green alga Chlamydomonas (Chlamydomonas reinhardtii) maintains efficient phototrophic growth in ambient or low CO2 environments by establishing a carbon concentrating mechanism

RNA folding kinetics control riboswitch sensitivity in vivo
Nature CommunicationsRiboswitches are ligand-responsive gene-regulatory RNA elements that perform key roles in maintaining cellular homeostasis. Understanding how riboswitch sensitivity to ligand (EC50) is controlled is critical to explain how highly conserved aptamer ...

Using a Riboswitch Sensor to Detect Co2+/Ni2+ Transport in E. coli
Frontiers in Chemistry, 2021 Intracellular concentrations of essential mental ions must be tightly maintained to avoid metal deprivation and toxicity. However, their levels in cells are still difficult to monitor. In this report, the combination of a Co2+Ni2+-specific riboswitch and

Carba-sugars Activate the glmS-Riboswitch of Staphylococcus aureus [PDF]
, 2011 The glmS-riboswitch is unique among riboswitch families as it represents a metabolite-dependent ribozyme that undergoes self-cleavage upon recognition of glucosamin-6-phosphate.

Synthesis of O6-alkylated preQ1 derivatives
Beilstein Journal of Organic Chemistry, 2021 A naturally occurring riboswitch can utilize 7-aminomethyl-O6-methyl-7-deazaguanine (m6preQ1) as cofactor for methyl group transfer resulting in cytosine methylation.

Ribozymes for RNA‐Catalyzed RNA Methylation and Labeling
Angewandte Chemie International Edition, Volume 65, Issue 23, 1 June 2026.Ribozymes are powerful tools for site‐specific RNA modification. Their activities range from installing tags and fluorophores to generating natural RNA methylations, making them valuable tools to uncover the many functions that RNA plays in nature.

The long and the short of riboswitches [PDF]
Current Opinion in Structural Biology, 2009 Regulatory mRNA elements or riboswitches specifically control the expression of a large number of genes in response to various cellular metabolites. The basis for selectivity of regulation is programmed in the evolutionarily conserved metabolite-sensing regions of riboswitches, which display a plethora of sequence and structural variants.
