FIG. 2.

Multiple-sequence alignment of the predicted translation of rainbow trout cathelicidins rtCATH_1 and rtCATH_2 and Atlantic salmon cathelicidins asCATH_1 and asCATH_2. Identical residues (indicated by asterisks) and similar residues (indicated by periods or colons) identified by the CLUSTAL program are indicated. The conserved motifs encoded by exon IV in each sequence are boxed. The cysteines involved in disulfide bond formation are in boldface text and are indicated with a percent sign. The predicted mature peptides are in italics, and the signal peptide is indicated by a bar above the alignment.
