RECOMBINANT PLASMID pPA-OPRFI DNA CODING HYBRID RECOMBINANT F-I PROTEIN OF Pseudomonas aeruginosa OUTER MEMBRANE, STRAIN Escherichia coli PA-OPRFI PRODUCING HYBRID RECOMBINANT F-I PROTEIN OF Pseudomonas aeruginosa OUTER MEMBRANE AND METHOD FOR PRODUCING HYBRID RECOMBINANT F-I PROTEIN OF Pseudomonas aeruginosa OUTER MEMBRANE

摘要

FIELD: medicine, pharmaceutics.SUBSTANCE: invention refers to biotechnology and concerns recombinant plasmid pPA-OPRFI DNA coding hybrid recombinant F-I protein of Pseudomonas aeruginosa outer membrane, of the bacterial strain E.coli PA-OPRFI producing this hybrid protein, and a method for producing this recombinant protein. The presented plasmid DNA contains a DNA fragment containing a sequence of modified promoter of bacteriophage T5 and two lactose operons; a DNA fragment containing a ribosome entry site, an initiation ATG-codon and a sequence coding six histidines; a DNA fragment containing the full-size sequences of oprF and opri genes of P.aeruginosa; a DNA fragment containing a ribosome entry site, and a DNA fragment containing a lambda ttranscription stop region.EFFECT: presented inventions enables producing the hybrid recombinant F-I protein of Paeruginosa outer membrane for carrying out an immunobiological assay in developing a Pseudomonas aeruginosa vaccine, and also for producing donor immunoglobulins for therapy of active forms of Paeruginosa infection.3 cl, 3 dwg, 1 tbl, 4 ex
