Alignment of the predicted amino acid sequences of four related C. felis chymotrypsin-like serine protease genes. Residues identical to sequence B2 are shown as dashes. The predicted N-terminal signal peptide for secretion is underlined. The catalytic triad residues are in bold and shaded. Conserved cysteines are marked with an asterix and the primary substrate determinant residue with an ‘s’. Residues differing between S16 and CfSP-25 are double-underlined
