Fig. 1From: Characterization of a novel aspartyl protease inhibitor from Haemonchus contortus Alignment of H. contortus API with aspins from other nematodes. The amino acid sequence of H. contortus API is compared with those from C. elegans (AAC46663), T. colubriformis (AY189824) and O. ostertagi (CAD10783). The conserved cysteine residues and cleavage sites are marked by ■ and ★. “RDL” motif is indicated by ▲. Putative signal sequence is overlinedBack to article page
