Based on the cloning FeSOD gene of the HZNH, the recombinant prokaryotic expression vector, PQESOa/FeSOD, was constructed and digested with restriction endonuclease BamH I and Pst I to check its construction. The PQE30a/FeSOD was then transformed into E.coli Ml5 and induced with IPTG. The high expression in vitro was obtained and analyzed on SDS-PAGE gel. The*results showed that the target proteins held a 37% portion in whole bacterial proteins and consisted of two parts, the soluble proteins and inclusion bodies. The soluble proteins in the aqueous layer, checked by means of activities of FeSOD enzymes and analyzed by means of activities of isozymogram from PAGE, demonstrated the induced expression proteins had the active nature of FeSOD enzymes.
