Thermodynamics of ligand-nucleic acid interactions.

Methods in enzymology, 1992
Ligand-and protein-DNA equilibria are extremely sensitive to solution conditions (e.g., salt, temperature, and pH), and, in general, the effects of different solution variables are interdependent (i.e., linked). As a result, an assessment of the basis for the stability and specificity of ligand-or protein-DNA interactions requires quantitative studies ...

Thermodynamic study of hybridization properties of heterochiral nucleic acids

Biochemical and Biophysical Research Communications, 2003
Heterochiral DNA and RNA heptamers, which contained an unnatural L-nucleotide, were synthesized, and thermodynamic analyses of their hybridization properties with complementary DNA and RNA strands were systematically conducted by UV melting experiments.

Thermodynamic Characterization of Nucleic Acid Nanoparticles Hybridization by UV Melting

2023
The advances in nucleic acid nanotechnology have given rise to various elegantly designed structural complexes fabricated from DNA, RNA, chemically modified RNA strands, and their mixtures. The structural properties of NA nanoparticles (NANP) generally dictate and significantly impact biological function; and thus, it is critical to extract information

Quantitative nucleic acids footprinting: thermodynamic and kinetic approaches

Current Opinion in Biotechnology, 1997
Quantitative footprinting techniques allow a detailed analysis of the thermodynamic forces that characterize nucleic acid-ligand interactions and ligand-induced changes in nucleic acid structure by separately resolving the intrinsic and cooperative Gibbs free energy changes describing the reactions being investigated.

Protein-nucleic acid thermodynamic databases for specific uses.

Trends in biotechnology, 2023
In response to Gromiha and Harini, we review the currently available thermodynamic databases for protein-nucleic acid interactions. These databases are designed for particular uses. We give general comments on them to facilitate browsing and exploration.

A Spectroscopic and Thermodynamic Study of Taxol Nucleic Acid Complexes

Nucleosides and Nucleotides, 1999
The interactions of natural and synthetic polynucleotide double strands with the antitumor agent paclitaxel and the oncological product "Taxol for Injection Concentrate" (abbreviated as taxol) were examined in diluted aqueous solutions by thermal denaturation profiles (Tm), CD spectra and UV-absorption measurements.

Thermodynamic databases for proteins and protein-nucleic acid interactions

Biopolymers, 2001
Thermodynamic data regarding proteins and their interactions are important for understanding the mechanisms of protein folding, protein stability, and molecular recognition. Although there are several structural databases available for proteins and their complexes with other molecules, databases for experimental thermodynamic data on protein stability ...

The Thermodynamic Basis of the Stability of Proteins, Nucleic Acids, and Membranes

1976
Publisher Summary The contributions of the polar and nonpolar components of the proteins and nucleic acids can be regarded as constituting the bricks and mortar, respectively, of the two structures. This chapter describes the changes in enthalpy and entropy of reactions as diverse as denaturation, ligand binding, and self-association display a ...
