Multiple sequence alignments of the RNA-binding domain in ribonuclease 3. The sequences were retrieved from public databases from the top to the bottom as abbreviated names of the following: Pseudomonas solanacearum, Dechloromonas aromatic, Shigella boydii serotype 4, Psychrobacter arcticum, Ehrlichia canis, Listeria monocytogenes serotype 4b, Staphylococcus aureus, Dehalococcoides ethenogenes, Dehalococcoides sp., Desulfotalea psychrophila, Aquifex aeolicus, Leptospira interrogans, Fusobacterium nucleatum, Treponema denticola, Campylobacter jejuni, Chlorobium chlorochromatii, Mimivirus, Treponema pallidum, Mycobacterium leprae, Rhodopirellula baltica, Caenorhabditis elegans, human, Tropheryma whipplei, Anabaena sp., Chlamydia trachomatis, and yeast. Strictly conserved and less strictly conserved amino acids are indicated with stars and solid doubled dots, respectively.
