    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 .lambda. P.sub.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: The subject invention provides an enzymatically active nonglycosylated, recombinant, human acetylcholinesterase comprising at least one polypeptide characterized by an amino acid sequence which is substantially identical to the amino acid sequence of naturally-occurring human acetylcholinesterase. The subject invention additionally provides an enzymatically active recombinant human acetylcholinesterase comprising at least one polypeptide characterized by an amino acid sequence in which serine is substituted for cys 611 in the sequence of naturally-occurring, human acetylcholinesterase and an enzymatically active recombinant human acetylcholinesterase comprising at least one polypeptide characterized by the presence of a methionine of the N-terminus of the amino acid sequence of naturally-occurring human acetylcholinesterase.
