Comparison of amino acid sequences among 29 porcine β-defensin genes. Amino acid sequences were predicted from cDNA sequences and aligned using ClustralW2 with minor manual manipulations to maximize sequence alignment. The 6-cysteine motifs are shaded. The 9 significantly conserved sites, including the 6-cysteine motif, are indicated at the bottom.
