    Abstract: A genomic gene encoding of human alpha-1-antitrypsin was cloned into a plasmid pET8C. E.coli BL21 (DE3) was transformed by the recombinant plasmids and a transformant (KCTC 0009BP) carrying the recombinant plasmid pEAT8 was screened. The transformant was cultured in a M9ZB medium at 37 deg.C and IPTG (0.04 mM) was added to the culture at OD600 = 0.7. After incubation at 40 deg.C for 3 hrs, the cell pellet was recovered by centrifugation. The cell pellet was treated by sonication and the precipitate containing alpha-1- antitrypsin was recovered by centrifugation. The precipitate was dissolved in a buffer containing 8M area and the alpha-1-antitrypsin was purified by DEAE-Sephacel chromatography and Mono-Q chromatography of FPLC.

    Abstract: The mutagenized recombinant AT of the present invention wherein some amino acids of the amino acid sequence of a wild-type AT are replaced with another amino acid, which has an enhanced thermoresistance compared to the wild-type AT while maintaining its activity. A vector containing a gene encoding the recombinant AT, a microorganism transformed with the vector and a process for producing the recombinant AT with a higher thermoresistance using the microorganism are also disclosed.
