Conservation of the Kunitz domain. Exons encoding Kunitz domains were translated and the resulting peptide sequences were aligned using CLUSTALW. The amino acid residues homologous with those of the peptidase binding loop (P3-P'3) in BPTI are framed and the P1 position is shaded. Positions with mutated Cys in SPINT4 and WFDC6 are framed and shaded.
