beta-Defensins are cationic antimicrobial peptides showing little sequence similarity but highly conserved tertiary structure stabilized by a six-cysteines-motif. Using a PCR approach, we described beta-defensin sequences with two exons in three species of Colubridae snakes with high sequence similarity between them. The deduced amino acid sequence presented the characteristics of beta-defensin family. The phylogenetic analysis using beta-defensin coding sequences of different snakes grouped them in two main branches: genes organized in three or two exons. (C) 2018 Elsevier Ltd.
