    • This invention is directed to genetically engineered proteins having human ChE activity, and more particularly, the activity of human AChE or human pseudo-ChE. The invention also provides for DNA sequences encoding such proteins, and more specifically DNA sequences comprising the entire coding region for encoding such complete proteins, and DNA expression vectors comprising such sequences. The invention also provides for DNA, which as been joined outside living cells, capable of infecting culturable cells, to be maintained therein and in progenies thereof which is adapted to encode such active proteins. The invention further provides culturable cells infected with recombinant DNA defined above, and to purified proteins having human ChE activity produced by such cells. There are further provided antibodies interacting with human AChE and pseudo-ChE and assays based on the use of such antibodies. The invention also provides compositions counteracting the effects of succinylcholine and of organophosphorus, containing as active ingredient an effective dosage of proteins defined above.
    • 本发明涉及具有人ChE活性的基因工程蛋白质,更具体地说,涉及人AChE或人类伪ChE的活性。 本发明还提供了编码这种蛋白质的DNA序列,更具体地,包括编码这种完整蛋白质的整个编码区的DNA序列,以及包含这些序列的DNA表达载体。 本发明还提供了能够感染可培养细胞的活体细胞外的DNA,其被保持在其中,并且其后代适于编码这种活性蛋白质。 本发明还提供了用上述定义的重组DNA感染的可培养细胞,以及由这些细胞产生的具有人ChE活性的纯化蛋白质。 进一步提供与人AChE和假ChE相互作用的抗体以及基于使用这种抗体的测定。 本发明还提供了抵消琥珀酰胆碱和有机磷的作用的组合物,其含有作为活性成分的有效剂量的上述蛋白质。
