Patent ID: 8865428

Claim:
A method for production of a protein (A) in the form of a fusion protein, comprising the steps of (a) preparing a DNA which codes for a fusion protein comprising the peptide chain forming the protein (A) and a second peptide chain (B), wherein the N-terminus of protein (A) is fused to the C-terminus of peptide (B) either directly or via a spacer; or the C-terminus of protein (A) is fused to the N-terminus of peptide (B) either directly or via a spacer, wherein the peptide chain (B) consists of a part of the amino acid sequence that starts with Ile696 and ends with Glu1180 of SEQ ID NO: 89, and the part comprises the sequence set forth in SEQ ID NO: 6, (b) introducing the DNA into a host bacterium, and (c) expressing the fusion protein in the host bacterium.
