Tertiary Motifs in RNA Structure and Folding.
Specific tertiary structural motifs determine the complete architecture of RNA molecules (see picture for examples). Within the last few years a number of high-resolution crystal structures of complex RNAs have led to new insights into the mechanisms by which these complex folds are attained. In this review the structures of these tertiary motifs and how they influence the folding pathway of bi...
متن کاملFolding and finding RNA secondary structure.
Optimal exploitation of the expanding database of sequences requires rapid finding and folding of RNAs. Methods are reviewed that automate folding and discovery of RNAs with algorithms that couple thermodynamics with chemical mapping, NMR, and/or sequence comparison. New functional noncoding RNAs in genome sequences can be found by combining sequence comparison with the assumption that function...
متن کاملRNA Secondary Structure Prediction Using Hierarchical Folding
Algorithms for prediction of RNA secondary structure— the set of base pairsthat form when an RNA molecule folds— are valuable to biologists who aim tounderstand RNA structure and function. Improving the accuracy and efficiencyof prediction methods is an ongoing challenge, particularly for pseudoknottedsecondary structures, in which base pairs overlap. This challenge is biologica...
متن کاملRNA folding causes secondary structure rearrangement.
The secondary structure of the P5abc subdomain (a 56-nt RNA) of the Tetrahymena thermophila group I intron ribozyme has been determined by NMR. Its base pairing in aqueous solution in the absence of magnesium ions is significantly different from the RNA in a crystal but is consistent with thermodynamic predictions. On addition of magnesium ions, the RNA folds into a tertiary structure with grea...
متن کاملSETTER - RNA SEcondary sTructure-based TERtiary Structure Similarity Algorithm
The recent interest in function of various RNA structures, reflected in the growth of solved RNA structures in PDB, calls for methods for effective and efficient similarity search in RNA structural databases. Here, we propose a method called SETTER (RNA SEcondary sTructurebased TERtiary structure similarity) based on partitioning of RNA structures into so-called generalized secondary structure ...
