    摘要: An improved vector which upon introduction into a suitable host containing the thermolabile repressor C I renders the host capable of effecting expression of a desired gene. The vector is a double-stranded DNA molecule which includes in 5' to 3' order the following: the promoter and operator P L O L from lambda bacteriophage; the N utilization site; a first restriction enzyme site which follows thereafter; a ribosomal binding site; an ATG initiation codon or DNA which is converted into an ATG initiation codon upon insertion of the desired gene into the vector; a second restriction enzme site for inserting the gene in phase with the ATG initiation codon; an origin of replication and either a gene associated with a selectable or identifiable phenotypic trait manifested when the vector is present in the host or a fragment designated cI⁴³⁴ which includes the gene for the cI⁴³⁴ repressor protein and its associated promoter and operator. The distance between the 3' end of P L O L and the 5' end of the N utilization site is less than about 80 base pairs. The distance between the 3' end of the N utilization site and the 5' end of the ribosomal binding site is less than about 300 base pairs. Vectors of the invention may also include a T₁T₂ rRNA transcription termination sequence located 3' of the second restriction enzyme site. The inventive vectors may have origin of replications capable of autonomous production in the host of at least 400 constitutive copies. Plasmids have been constructed from the vectors and used to produce bovine, chicken, porcine and human growth hormones, human apolipoprotein E and human superoxide dismutase and analogs thereof in host cells. Such superoxide dismutase or analogs thereof may be used to catalyze the reduction of superoxide radicals, reduce reperfusion injury, prolong the survival time of isolated organs and prevent neurological injury. Enzymatically active eucaryotic superoxide dismutase or an analog thereof may also be produced by an improved method of this invention which employs a production medium having a concentration of Cu⁺⁺ greater than about about 2ppm. The invention also concerns improved methods of recovering purified enzymatically active eucaryotic superoxide dismutase or analogs thereof.

    摘要: Plasmids are provided which upon introduction into a suitable Escherichia coli host render the host capable of effecting expression of DNA encoding a desired natu­rally-occurring polypeptide or polypeptide analog thereof under the control of the deo P1-P2 promoter. Further plasmids are also provided which thermoin­ducibly direct expression of eucaryotic genes under the control of a λ P L promoter and a thermolabile repressor protein present on the same plasmid under the control of a deo P1 promoter. These plasmids have been insert­ed into various hosts, some of which contain DNA encod­ing the repressor protein.
    Such plasmids may be used to produce polypeptides such as human copper/zinc superoxide dismutase, hMnSOD-hGPX fusion polypeptides, human manganese superoxide dismutase, human growth hormone, bovine growth, porcine growth, human growth hormone-apolipoprotein E fused polypeptides, apolipoprotein E and various fibronectin domains.

    摘要: A double-stranded cDNA molecule which includes DNA encoding human manganese superoxide dismutase has been created. The sequence of one strand of a double-­stranded DNA molecule which encodes human manganese superoxide dismutase has been discovered. Such mole­cules may be introduced in prokaryotic, e.g., bacteri­al, or eucaryotic, e.g., yeast or mammalian, cells and the resulting cells cultured or grown under suitable conditions so as to produce human manganese superoxide dismutase, human manganese superoxide dismutase analogs or human manganese superoxide dismutase mutants which may then be recovered. By this invention, human man­ganese superoxide dismutase gene fragments from various plasmids may be ligated to yield a complete genomic human manganese superoxide dismutase gene fragment. Human manganese superoxide dismutase, analogs, or mu­tants may be used to catalyze the reduction of superoxide radicals, reduce reperfusion injury, pro­long the survival time of isolated organs, or treat inflammations. The invention also concerns a method of producing enzy­matically active human manganese superoxide dismutase compounds in a bacterial cell which contains and is capable of expressing a DNA sequence encoding the superoxide dismutase compound by maintaining the bac­ terial cell under suitable conditions and in a suit­able production medium. The production medium is sup­plemented with an amount of Mn⁺⁺ so that the concentra­tion of Mn⁺⁺ in the medium is greater than about 2 ppm. Genomic manganese superoxide dismutase DNA should also be capable of expression in eucaryotic cells under suitable conditions. This invention also concerns a method of recovering purified enzymatically active manganese superoxide dismutase, analogs or mutants from bacterial cells. It should also be possible to recover manganese SOD from genomic manganese superoxide dismutase DNA expressed in eucaryotic cells using similar methods. The invention further concerns uses of the human manga­nese superoxide dismutase, human manganese superoxide dismutase analogs or human manganese superoxide dismutase mutants, various new analogs, compositions of the compounds and methods of treating various disorders using these compositions.
