PRODUCTION OF PROTEINS BY AUTOPROTEOLYTIC CLEAVAGE

摘要

The present invention relates to a process for the production of a desired heterologous polypeptide with a clearly defined homogeneous N-terminus in a bacterial host cell, wherein the desired heterologous polypeptide is autoproteolytically cleaved from an initially expressed fusion protein which comprises a polypeptide with the autoproteolytic activity of an autoprotease Npro of a pestivirus and the heterologous polypeptide by the Npro autoproteolytic activity.
