MOTIVATIONS Biclustering is a clustering method that simultaneously clusters both the domain and range of a relation. A challenge in multiple sequence alignment (MSA) is that the alignment of sequences is often intended to reveal groups of conserved functional subsequences. Simultaneously, the grouping of the sequences can impact the alignment; precisely(More)
A collection of diverse 16S and 16S-like rRNA secondary structure diagrams are available. This set of rRNAs contains representative structures from all of the major phylogenetic groupings--Archaea, (eu)Bacteria, and the nucleus, mitochondrion, and chloroplast of Eucarya. Within this broad phylogenetic sampling are examples of the major forms of structural(More)
INTRODUCTION This compilation is part of an ongoing effort to maintain a comprehensive and continually updated collection of large subunit (LSU; 23S and 23S-like) rRNA secondary structures and associated sequence and citation information. Table 1 gives a breakdown of the number and phylogenetic distribution of sequences currently in this LSU rRNA database.(More)
With an increasingly large amount of sequences properly aligned, comparative sequence analysis can accurately identify not only common structures formed by standard base pairing but also new types of structural elements and constraints. However, traditional methods are too computationally expensive to perform well on large scale alignment and less effective(More)
Beyond its direct involvement in protein synthesis with mRNA, tRNA, and rRNA, RNA is now being appreciated for its significance in the overall metabolism and regulation of the cell. Comparative analysis has been very effective in the identification and characterization of RNA molecules, including the accurate prediction of their secondary structure. We are(More)
A new and emerging paradigm in molecular biology is revealing that RNA is implicated in nearly every aspect of the metabolism in the cell. To enhance our understanding of the function of these RNA molecules in the cell, it is essential that we have a complete understanding of their higher-order structures. While many computational tools have been developed(More)
—We present a fast pairwise RNA sequence alignment method using structural information, named R-PASS (RNA Pairwise Alignment of Structure and Sequence), which shows good accuracy on sequences with low sequence identity and significantly faster than alternative methods. The method begins by representing RNA secondary structure as a set of structure motifs.(More)
