RNA approaches the B‐form in stacked single strand dinucleotide contexts

  title={RNA approaches the B‐form in stacked single strand dinucleotide contexts},
  author={Ada Sedova and Nilesh K. Banavali},
Duplex RNA adopts an A‐form structure, while duplex DNA interconverts between the A‐ and B‐forms depending on the environment. The C2′‐endo sugar pucker seen in B‐form DNA can occur infrequently in ribose sugars as well, but RNA is not understood to assume B‐form conformations. Through analysis of over 45,000 stacked single strand dinucleotide (SSD) crystal structure conformations, this study demonstrates that RNA is capable of adopting a wide conformational range between the canonical A‐ and B… 
Geometric Patterns for Neighboring Bases Near the Stacked State in Nucleic Acid Strands.
A reduced set of stacking geometries is directly useful for stacking-energy comparisons between empirical force fields, prediction of plausible localized variations in single-strand structures near their canonical states, and identification of analogous stacking patterns in newly solved nucleic acid containing structures.
The extent of B-form structure in a 6S RNA variant that mimics DNA to bind to the Escherichia coli RNA Polymerase
A different structural analysis based on conformational distance from canonical A-form and B-form single-strand structures is presented, addressing the occurrence and extent of both local and global B- form structure in the published 6S RNA variant model.
Coarse-Grained Double-Stranded RNA Model from Quantum-Mechanical Calculations.
The development of the coarse-grained model for RNA allows extending the spatial and temporal length scales accessed by computer simulations and being able to model RNA-related biophysical processes, as well as novel RNA nanostructures.
Structural Bioinformatics: Life Through The 3D Glasses
In order to have comprehensive understanding of biological systems, one requires sound understanding of fundamentals of macromolecular structure, its experimental determination, or prediction using computational approaches, data representation, visualization, and integration.
Effects of hydroxyapatite (0001) Ca2+/Mg2+ substitution on adsorbed D-ribose ring puckering
Results show that when replacement by Mg2+ occurs in OH−-coordinated Ca2+ ions, Mg1+⋯D-ribose interactions are strong enough to prevent the interactions between the hydroxyl groups of the sugar and the remaining Ca2+.

Tensor decompositions for the bubbles and cube numerical framework
It is demonstrated that SXC is suitable for the enrichment of ssRNA and dsRNA viral genomes from contaminating cellular RNA species and has the potential to separate dsRNAs from ssRNAs of the same length.
A Proposal for a New Biological Supercomputer based Exclusively on RNA Molecules, Quantum Mechanics and Nanoptics
In this paper, we propose a biological supercomputer which is based in RNA molecules. Biological computers are made from living cells. Instead of electrical wiring and signaling, biological computers


A-form conformational motifs in ligand-bound DNA structures.
The collective data provide new structural details on the conformational pathway connecting A and B-form DNA and illustrate how both proteins and drugs take advantage of the intrinsic conformational mechanics of the double helix.
C2′-endo nucleotides as molecular timers suggested by the folding of an RNA domain
It is demonstrated that formation of a single stacking interaction at a C2′-endo nucleotide comprises the rate-determining step for folding an entire 154 nucleotide RNA.
Slow conformational dynamics at C2'-endo nucleotides in RNA.
It is concluded that the C2'-endo conformation by itself does not govern SHAPE reactivity, however, some C2-endo nucleotides undergo extraordinarily slow conformational changes, on the order of 10(-4) s(-1).
Free energy landscape of A-DNA to B-DNA conversion in aqueous solution.
The absolute minimum in the calculated free energy profile corresponds closely to the crystal structure of the hexamer sequence, indicating that the present method has the potential to identify the most stable state for an arbitrary DNA sequence in water.
Stepping through an RNA structure: A novel approach to conformational analysis.
The pseudotorsional convention described here should significantly simplify approaches to macromolecular modeling of RNA structure, and provide a two-dimensional representation of the conformational properties of an entire RNA molecule, facilitating rapid analysis of structural features.
Structure of a triple helical DNA with a triplex-duplex junction.
A novel design of DNA sequences is reported, which allows the first crystallographic study of DNA segment containing triplexes and its junction with a duplex and there are large changes in the phosphate backbone torsion angles of the purine strand that may represent sequence-specific structural variations of the DNA triplex.
