<p>The invention relates to biotechnology, gene engineering, the microbiological and medical industries. The aim of said invention is to develop a recombinant carrier protein for address delivering a plasmid DNA to selected target cells. The inventive recombinant protein comprises three structure functional domains integrated into the following single polypeptide chain: a DNA-binding domain, a toxin and streptavidine . Said invention also involves the construction of the gene of a recombinant fused protein carrier by combining coding sequences of said three functional domains and isolating and purifying said recombinant protein.</p> |
