Structural characteristics are essential for the functioning of many noncoding RNAs and cis-regulatory elements mRNAs. SNPs may disrupt these structures, interfere with their molecular function, hence cause a phenotypic effect. RNA folding algorithms can provide detailed insights into structural effects SNPs. The global measures employed so far suffer from limited accuracy programs on large computationally too demanding genome-wide applications. Here, we present strategy that focuses local...

Computational methods for determining the secondary structure of RNA sequences from given alignments are currently either based on thermodynamic folding, compensatory base pair substitutions or both. However, there is no approach that combines both sources information in a single optimization problem. Here, we present model formally integrates energy-based and evolution-based approaches to predict folding multiple aligned sequences. We have implemented an extended version Pfold identifies...

Structured elements of RNA molecules are essential in, e.g., stabilization, localization, and protein interaction, their conservation across species suggests a common functional role. We computationally screened vertebrate genomes for conserved structures (CRSs), leveraging structure-based, rather than sequence-based, alignments. After careful correction sequence identity GC content, we predict ∼516,000 human genomic regions containing CRSs. find that substantial fraction human-mouse CRS (1)...

Predicting RNA-RNA interactions is essential for determining the function of putative non-coding RNAs. Existing methods prediction are all based on single sequences. Since comparative have already been useful in RNA structure determination, we assume that conserved also imply function. Of these, further a non-negligible amount existing acquired compensating base changes throughout evolution. We implement method, PETcofold, can take covariance information intra-molecular and inter-molecular...

Clustering RNA sequences with common secondary structure is an essential step towards studying function. Whereas structural alignment strategies typically identify for orthologous structured RNAs, clustering seeks to group paralogous RNAs based on similarities. However, existing approaches do not take the compensatory base pair changes obtained from conservation in into account.

Bacillus subtilis is a Gram-positive bacterium used as cell factory for protein production. Over the last decades, continued optimization of production strains has increased yields enzymes, such amylases, and made commercial applications feasible. However, current are still significantly lower than theoretically possible yield based on available carbon sources. In its natural environment, B. can respond to unfavorable growth conditions by differentiating into motile cells that use flagella...
