    摘要: The invention relates to a method for producing biologically active β-NGF from the proform proNGF. After expressing the proform of the β-NGF in a prokaryotic host cell, the recombinant protein is isolated in the form of insoluble inactive aggregates (inclusion bodies). After the solubilization thereof in a strong denaturing agent and the subsequent conversion thereof into the natural conformation, which is determined by the disulfide bridges present in the natural β-NGF, biologically active β-NGF is obtained by subsequently splitting-off the prosequence.

    摘要: A pro-polypeptide which is useful for the expression of a polypeptide of interest in a prokaryotic cell. Therefore the pro-polypeptide is fused to the N-terminus of the polypeptide of interest. The pro-polypeptide as reported herein provides for improved expression yields and improves the handling of the fusion polypeptide (downstream processing, purification). For example, efficient endotoxin removal is effected while the protein of interest comprising the pro-polypeptide is bound e.g. to an affinity chromatography material. Thereafter the pro-polypeptide can efficiently be cleaved from the polypeptide of interest by the incorporated protease cleavage site with the cognate protease.
