    摘要: The invention relates to modified proteins of the superfamily of “ubiquitin-like proteins”, proteins that have a ubiquitin-like fold and fragments or fusion proteins thereof. As a result of said modification, the proteins have a binding affinity with respect to a predetermined binding partner that did not exist previously. The invention also relates to a method for the production and utilization of said proteins.

    摘要: A process produces a water-soluble, naturally folded eukaryotic polypeptide containing two or several cysteines linked by disulfide bridges. This process involves culturing prokaryotic cells, a) in which the prokaryotic cells contain an expression vector which encodes the polypeptide which contains a prokaryotic signal sequence at the N-terminus, b) under conditions under which the polypeptide is secreted into the periplasm or the medium, c) cleaving the signal sequence and isolating the polypeptide from the periplasm or the medium. In this process, the culturing is carried out in the presence of arginine or a compound of the formula I R2—CO—NR1 (I) in which R and R1 represent hydrogen or a saturated or unsaturated branched or unbranched C1-C4 alkyl chain and R2 represents hydrogen, NHR1 or a saturated or unsaturated branched or unbranched C1-C3 alkyl chain, is suitable for the recombinant production of polypeptides in prokaryotes in a high yield.
