摘要

1. Claims for the Contracting States : BE, CH, DE, FR, GB, IT, LI, LU, NL, SE A fusion protein of the general formula Met - Xn - D' - Y - Z in which n is zero or 1, X is a sequence of 1 to 12 genetically codable amino acids, D' is a sequence of about 70 amino acids in the region of the sequence of amino acids 23 - 93 of the D-peptide in the trp operon of E. coli, Y denotes a sequence of one or more genetically codable amino acids which permits the following amino acid sequence Z to be cleaved off, and Z is a sequence of genetically codable amino acids. 1. Claims for the Contracting State : AT A process for the preparation of a fusion protein of the general formula (1) Met - Xn - D' - Y - Z in which n is zero or 1, X is a sequence of 1 to 12 genetically codable amino acids, D' is a sequence of about 70 amino acids in the region of the sequence of amino acids 23 - 93 of the D-peptide in the trp operon of E. coli, Y denotes a sequence of one or more genetically codable amino acids which permits the following amino acid sequence Z to be cleaved off, and Z is a sequence of genetically codable amino acids, characterized by expressing a gene structure which codes for these fusion proteins in a host cell, and separating the fusion protein.
