ENHANCED EXPRESSION OF FUSION POLYPEPTIDES WITH A BIOTINYLATION TAG

摘要

The invention provides the means to enhance in E.coli-based expression systems the formation of fusion polypeptides containing as an N-terminal tag a biotinylation polypeptide. By way of specifically exchanging in the nucleic acid sequence encoding the biotinylation polypeptide nucleotides at 11 discrete positions enhances the formation of the total fusion polypeptide by at least 40%.
