abstract：:Recently, a new serine protease inhibitor family has been described in arthropods. Eight members were purified from locusts and 13 peptides have been identified by cDNA cloning. The peptides share a conserved cysteine array (Cys-Xaa(9-12)-Cys-Asn-Xaa-Cys-Xaa-Cys-Xaa(2-3)-Gly-Xaa(3-6)-Cys-Thr-Xaa(3)-Cys) with nine inhi...
