Supplementary Data: Discovery of natural non-circular permutations in non-coding RNAs

<strong>Supplementary File 1</strong>. RNAMotif Rnamotif / DARN! search patterns for the new permutations of the hammerhead ribozyme and analogous twister ribozyme permutations. <strong>Supplementary File 2</strong>. Alignments of novel RNA motifs detected in this work (Supplementary Table 2). The alignments are stored in Stockholm format, which is a text format that can be viewed with a fixed-width font and can also be interpreted by several computer programs. Only unique sequences are supplied. <strong>Supplementary File 3</strong>. Printable alignments of novel RNA motifs detected in this work (Supplementary Table 2), in PDF format. Only unique sequences are shown. <strong>Supplementary File 4</strong>. Frequencies of RNA motifs in different environmental datasets. This data is a basis for relevant columns in Supplementary Table 2. The first worksheet describes the data format.
