Physics-based RNA structure prediction
Despite the success of RNA secondary structure prediction for simple, short RNAs, the problem of predicting RNAs with long-range tertiary folds remains. Furthermore, RNA 3D structure prediction is hampered by the lack of the knowledge about the tertiary contacts and their thermodynamic parameters. Low-resolution structural modeling enables us to estimate the conformational entropies for a numbe...
متن کاملHelix Capping in RNA Structure
Helices are an essential element in defining the three-dimensional architecture of structured RNAs. While internal basepairs in a canonical helix stack on both sides, the ends of the helix stack on only one side and are exposed to the loop side, thus susceptible to fraying unless they are protected. While coaxial stacking has long been known to stabilize helix ends by directly stacking two cano...
متن کاملCCG-Based RNA Secondary Structure Prediction
Various systems have been proposed to predict secondary structures of RNAs using their sequence information. Among them, Uemura et al. [2] described a system that recognizes some typical RNA secondary structures such as hairpin loops and pseudoknots with Tree Adjoining Grammar. However, their work captures only known sub-structures, and not those unknown sub-structures that might also exist. Te...
متن کاملiFoldRNA: three-dimensional RNA structure prediction and folding
UNLABELLED Three-dimensional RNA structure prediction and folding is of significant interest in the biological research community. Here, we present iFoldRNA, a novel web-based methodology for RNA structure prediction with near atomic resolution accuracy and analysis of RNA folding thermodynamics. iFoldRNA rapidly explores RNA conformations using discrete molecular dynamics simulations of input ...
متن کاملStructure of a mispaired RNA double helix at 1.6-A resolution and implications for the prediction of RNA secondary structure.
The nonamer r(GCUUCGGC)dBrU, where dBrU is 5-bromo-2'-deoxyuridine, contains the tetraloop sequence UUCG. It crystallizes in the presence of Rh(NH3)6Cl3. In solution the oligomer is expected to form a hairpin loop but the x-ray structure analysis, to a resolution of 1.6 A, indicates an eight-base-pair A-RNA duplex containing a central block of two G.U and two C.U pairs. Self-pairs which approxi...
