Phylogenetic relationship between zebra finch (zf_), chicken (gg_), and human (hs_) proteases in granzyme clusters. Numbers indicate the robustness of each node assessed by bootstrap. Azu1, azurocidin-1; df2, complement factor D; ela2, neutrophil elastase; prtn3, proteinase 3; gzm, granzyme; ela, elastase; cma1, chymase. Human azurocidin is included as an outgroup.
