Fig. 3. ClustalW alignment of insect chymotrypsin-like proteases. Amino acids that
are conserved, highly conserved or identical in all sequences are highlighted
in light grey, grey or black, respectively. Open triangle, conserved trypsin
cleavage site; filled triangles, conserved residues of the S1 specificity
pocket; arrows, residues of the catalytic triad of serine proteases;
asterisks, conserved cysteines; bar, putative N-glycosylation site
for CTLP1. Ms, Manduca sexta; Ag, Anopheles gambiae; Dm,
Drosophila melanogaster; CT, chymotrypsin.
