Tetramolecular quadruplex stability and assembly.
Guanine quadruplexes (G4) are unusual four-stranded nucleic acid structures formed by G-rich DNA/RNA. Beyond their likely biological relevance, the self-assembly, stability, and rigidity of these structures are also interesting for nanotechnology and biotechnology applications. Therefore, efforts are carried out to understand the rules that govern stability and folding of G-quadruplexes. We foc...
متن کاملStability and kinetics of G-quadruplex structures
In this review, we give an overview of recent literature on the structure and stability of unimolecular G-rich quadruplex structures that are relevant to drug design and for in vivo function. The unifying theme in this review is energetics. The thermodynamic stability of quadruplexes has not been studied in the same detail as DNA and RNA duplexes, and there are important differences in the bala...
متن کاملMetal Cations in G-Quadruplex Folding and Stability
This review is focused on the structural and physicochemical aspects of metal cation coordination to G-Quadruplexes (GQ) and their effects on GQ stability and conformation. G-quadruplex structures are non-canonical secondary structures formed by both DNA and RNA. G-quadruplexes regulate a wide range of important biochemical processes. Besides the sequence requirements, the coordination of monov...
متن کاملA Toolbox for Predicting G-Quadruplex Formation and Stability
G-quadruplexes are four stranded nucleic acid structures formed around a core of guanines, arranged in squares with mutual hydrogen bonding. Many of these structures are highly thermally stable, especially in the presence of monovalent cations, such as those found under physiological conditions. Understanding of their physiological roles is expanding rapidly, and they have been implicated in re...
متن کاملElectrostatics of nanowire transistors
S The electrostatics of nanowire transistors are studied by solving the Poisson equation self-consistently with the equilibrium carrier statistics of the nanowire. For a one-dimensional, intrinsic nanowire channel, charge transfer from the metal contacts is important. We examine how the charge transfer depends on the insulator and the metal/semiconductor Schottky barrier height. We also show th...
