A cDNA encoding aminopeptidase N was cloned by degenerated PCR combined with RACEtechnique in this paper. The full-length of APN-Harm is 3 043 bp. Open reading frame is 2 856 bp inlength, encoding 951 amino acid residues. Its predicted molecular weight and isoelectric point are 108.3kDa and 5.29, respectively. This deduced amino acid sequence shares some common structural features withaminopeptidase N from several moth species, including the consensus zinc-binding motif HEXXHX18 E and the GAMEN motif common to gluzincin aminopeptidases. The first 20 amino acid residues at N-termini ishydrophobic transmembrane helix. The sequence of APN-Harm was deposited in GenBank and the accessionnumber is AY181026.
