Multiple alignments of 17 deduced amino acid sequences of putative chymotrypsins and chymotrypsin homologs from <i>O. nubilalis</i> larvae using Clustal W2.

<p>The predicted signal peptide is underlined in brown; the catalytic triads and conserved regions are boxed in blue; the conserved catalytic triads are marked with blue arrows at the top; the autocatalytic site is marked with green arrow at the top; the conserved residue in the S1 pocket is marked with purple arrow at the top; and the six cysteine residues were marked with purple stars at the top.
