Interplay of 'induced fit' and preorganization in the ligand induced folding of the aptamer domain of the guanine binding riboswitch [PDF]
Riboswitches are highly structured elements in the 50-untranslated regions (50-UTRs) of messenger RNA that control gene expression by specifically binding to small metabolite molecules. They consist of an aptamer domain responsible for ligand binding and

Hidden Structural Modules in a Cooperative RNA Folding Transition
Summary: Large-scale, cooperative rearrangements underlie the functions of RNA in RNA-protein machines and gene regulation. To understand how such rearrangements are orchestrated, we used high-throughput chemical footprinting to dissect a seemingly ...

The architecture of the SARS-CoV-2 RNA genome inside virion
Secondary structures and long-range RNA interactions of the SARS-CoV-2 genome have been investigated by various sequencing methods. Here the authors use an RNA-RNA hybrid sequencing method to predict the secondary and tertiary structure of the SRAS-CoV-2

Influence of ground-state structure and Mg2+ binding on folding kinetics of the guanine-sensing riboswitch aptamer domain [PDF]
Riboswitch RNAs fold into complex tertiary structures upon binding to their cognate ligand. Ligand recognition is accomplished by key residues in the binding pocket.

Comparative analysis of RNA secondary structure accuracy on predicted RNA 3D models
RNA structure is conformationally dynamic, and accurate all-atom tertiary (3D) structure modeling of RNA remains challenging with the prevailing tools. Secondary structure (2D) information is the standard prerequisite for most RNA 3D modeling.

Structure of a rare non-standard sequence k-turn bound by L7Ae protein [PDF]
Kt-23 from Thelohania solenopsae is a rare RNA kink turn (k-turn) where an adenine replaces the normal guanine at the 2n position. L7Ae is a member of a strongly conserved family of proteins that bind a range of k-turn structures in the ribosome, box C/D

Novel endoribonucleases as central players in various pathways of eukaryotic RNA metabolism [PDF]
For a long time it has been assumed that the decay of RNA in eukaryotes is mainly carried out by exoribonucleases, which is in contrast to bacteria, where endoribonucleases are well documented to initiate RNA degradation.

Tertiary Hydrogen Bonds in the Solution Structure of Transfer RNA [PDF]
The high resolution nuclear magnetic resonance (NMR) spectra of hydrogen-bonded protons in four tRNAs have been studied at 270 MHz. The relative intensity of the resonances between -11 ppm and -15 ppm of Escherichia coli tRNA 1 Val ...
