FIG. 1.

ClustalW alignment (MacVector 6.5.3) of the deduced amino acid sequence of rPt-API-1 with orthologous sequences from other nematodes identified by BLASTp and tBLASTn searches. Amino acid positions are numbered along the margins. Conserved residues are indicated by the shaded boxed areas. The percent identities of orthologues to Pt-API-1 are indicated in the box at the lower right. Asterisks indicate four invariant conserved cysteine residues. The overline at the N terminus indicates the predicted signal peptide of P. tenuis.
