Abstract: A method for the production of polypeptides utilizing a polymer of charged amino acids and an exopeptidase. A DNA sequence coding for the charged amino acid polymer is inserted adjacent to one end of the polypeptide gene. The polypeptide-charged amino acid polymer fusion product is removed from most contaminants by selecting for the charged amino acid polymer during a first isolation step. Next the charged amino acid polymer is hydrolyzed using an exopeptidase which leaves the polypeptide active. A second isolation step removes the polypeptide from any remaining contaminents. An example using polyarginine and carboxypeptidase B to produce urogastrone is included.
