    • 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 procaryotic, e.g., bacterial, or eukaryotic, e.g., yeast or mammalian, cells and the resulting cells cultured or grown under suitable conditions so as to produce human manganese superoxide dismutase or analogs thereof which may then be recovered. By this invention, human MnSOD gene fragments from various plasmids may be ligated to yield a complete genomic human MnSOD gene fragment. Human MnSOD or analogs thereof 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 or an analog thereof in a bacterial cell which contains and is capable of expressing a DNA sequence encoding the superoxide dismutase by maintaining the bacterial 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 MnSOD 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 from bacterial cells. It should also be possible to recover manganese SOD from genomic MnSOD DNA expressed in eucaryotic cells using similar methods.
    • 已经产生了包含编码人锰超氧化物歧化酶的DNA的双链cDNA分子。 已经发现编码人锰超氧化物歧化酶的双链DNA分子的一条链的序列。 这样的分子可以在原核细胞中,例如细菌的,或真核的,例如酵母或哺乳动物细胞中引入,所得细胞在合适的条件下培养或生长,以产生可以被回收的人锰超氧化物歧化酶或其类似物。 通过本发明,可以连接各种质粒的人类MnSOD基因片段以产生完整的基因组人类MnSOD基因片段。 人类MnSOD或其类似物可用于催化超氧自由基的还原,减少再灌注损伤,延长分离的器官的存活时间或治疗炎症。本发明还涉及生产酶活性人锰超氧化物歧化酶或其类似物的方法 在细菌细胞中,其含有并且能够通过将细菌细胞维持在合适的条件下并在合适的生产培养基中表达编码超氧化物歧化酶的DNA序列。 生产培养基补充一定量的Mn ++,使得培养基中Mn ++的浓度大于约2ppm。 基因组MnSOD DNA也应该能够在合适条件下在真核细胞中表达。本发明还涉及从细菌细胞中回收纯化的酶活性锰超氧化物歧化酶的方法。 也可以使用类似的方法从真核细胞中表达的基因组MnSOD DNA中回收锰SOD。

    • A bacterial cell containing a functional cytochrome P450 monooxygenase system, said cell comprising a genetic construct capable of expressing a cytochrome P450 and genetic construct capable of expressing, separately from said cytochrome P450, a cytochrome P450 reductase, wherein each of the cytochrome P450 and the cytochrome P450 reductase have at their N-terminus a bacterial signal peptide. The cytochrome P450 and the cytochrome P450 reductase may be encoded by different constructs or the same construct. A bacterial cell containing a cytochrome P450 comprising a genetic construct encoding, and capable of expressing, said cytochrome P450 wherein the cytochrome P450 has, at is N-terminal, a bacterial signal peptide. The bacterial cells are useful as, for example, bioreactors, in drug testing and mutagenicity testing and as a source of cytochrome P450.
