Nucleic Acid Thermodynamics Derived from Mechanical Unzipping Experiments [PDF]
Life, 2022 Force-spectroscopy techniques have led to significant progress in studying the physicochemical properties of biomolecules that are not accessible in bulk assays. The application of piconewton forces with laser optical tweezers to single nucleic acids has

MeltR software provides facile determination of nucleic acid thermodynamics [PDF]
Biophysical Reports, 2023 Thermodenaturation (melting) curves of macromolecules are used to determine folding thermodynamic parameters. Notably, this insight into RNA and DNA stability underlies nearest neighbor theory and diverse structure prediction tools.

Optical melting measurements of nucleic acid thermodynamics. [PDF]
Methods Enzymol, 2009 Optical melting experiments provide measurements of thermodynamic parameters for nucleic acids. These thermodynamic parameters are widely used in RNA structure prediction programs and DNA primer design software. This review briefly summarizes the theory and underlying assumptions of the method and provides practical details for instrument calibration ...

The role of low-complexity repeats in RNA–RNA interactions and a deep learning framework for duplex prediction [PDF]
Nature CommunicationsRNA–RNA interactions (RRIs) are fundamental to gene regulation and RNA processing, yet their molecular determinants remain unclear. In this work, we analyze several large-scale RRI datasets and identify low-complexity repeats (LCRs), including simple ...

Thermodynamic analysis of Zα domain-nucleic acid interactions [PDF]
Biochemical Journal, 2022 AbstractDNA/RNA molecules adopting the left-handed conformation (Z-form) have been attributed with immunogenic properties. However, their biological role and importance has been a topic of debate for many years. The discovery of Z-DNA/RNA binding domains (Zα domains) in varied proteins that are involved in the innate immune response, such as the ...

Thermodynamic Analysis of Nylon Nucleic Acids [PDF]
ChemBioChem, 2008 AbstractThe stability and structure of nylon nucleic acid duplexes with complementary DNA and RNA strands was examined. Thermal denaturing studies of a series of oligonucleotides that contained nylon nucleic acids (1–5 amide linkages) revealed that the amide linkage significantly enhanced the binding affinity of nylon nucleic acids towards both ...

Monovalent metal ion binding promotes the first transesterification reaction in the spliceosome
Nature Communications, 2023 Cleavage and formation of phosphodiester bonds in nucleic acids is accomplished by large cellular machineries composed of both protein and RNA. Long thought to rely on a two-metal-ion mechanism for catalysis, structure comparisons revealed many contain ...
