Abstract
The aim of the invention is to improve the secretion of a protein from a host cell in order to increase the product yield of protein in a fermentation process. This is achieved by an expression vector comprising a) a promoter sequence and b) a nucleic acid sequence that codes for a protein. The protein comprises a signal peptide and an additional amino acid sequence, and the signal peptide comprises an amino acid sequence that is at least 80% identical to the amino acid sequence specified in SEQ ID NO: 2, at least 80% identical to the amino acid sequence specified in SEQ ID NO: 4, at least 80% identical to the amino acid sequence specified in SEQ ID NO: 6, or the signal peptide comprises an amino acid sequence that is structurally homologous to at least one of said sequences.
