    摘要: A method for preparing a soluble protein comprising urokinase-type plasminogen activator (uPA) or an active fragment thereof, or a variant of either of these which has uPA activity, which method comprises contacting said protein with a buffer at a pH of from 8.5-10.5, said buffer comprising a reducing agent and an oxidising agent which forms a redox pair, wherein the reducing agent is present in excess compared to the oxidising agent, and wherein the reducing agent is present in a concentration of at least 5 mM. Material obtainable in this way forms a further aspect of the invention. It has been refolded in a “native-like” form and is useful in studies such as N.M.R. analysis to detect ligands.

    摘要: Plasmids containing synthetic DNA sequences are described which are suitable for the expression of the intermediate protein of the recombinant scu-PA (i.e., the unglycosylated protein moiety of the single chain prourokinase) in Enterobacteriaceae, especially in E. coli, with expression rates far higher than those obtainable according to prior methods. The plasmids comprise operons that include a regulatable, optionally synthetic, promotor, a Shine-Dalgarno sequence, a start codon, a synthetic structural gene with selected codon usage, and downstream of the structural gene, 1 to 2 transcription terminators. The preparation of the plasmids and of synthetic DNA-sequences starting from commercially available plasmids and intermediates is described. The intermediate protein, expressed in high yields by using the plasmids for transforming suitable hosts, may be refolded to produce the therapeutically useful plasminogen activator recombinant scu-PA. This protein also may serve as a starting material for obtaining the recombinant two chain unglycosylated urokinase protein (rtcu-PA) on a large scale by splitting the single chain product.
