Figure 3From: Gain and loss of an intron in a protein-coding gene in Archaea: the case of an archaeal RNA pseudouridine synthase geneAlignment of cbf5 introns with their flanking sequences. The data was shaded by using the Boxshade server [57]. Residues conserved among more than 50% of the sequences are shown on black background. Residues similar to the conserved residue, or conserved among purines (or pyrimidines), are shown on gray background. The intron region and the region corresponding to the BHB motif (bulge as B, helix as H) are also shown.Back to article page
