  • Patent number: 5719021
    Abstract: A method is disclosed for producing a biochemically active polypeptide from a biochemically inactive polypeptide. The polypeptide is normally but need not be expressed in a precursor form containing a pro-sequence. The inactive polypeptide is reacted with a tailor-made activating peptide. The activating peptide can be synthetic or made by recombinant DNA procedure. The activating peptide is a peptide which contains one or more functional domains which are necessary for folding the inactive polypeptide into a biochemically active conformation. The activating peptide may but need not contain a sequence of amino acids which is identical to the sequence of the natural occurring pro-sequence of the polypeptide. Also, a method is disclosed which permits to identify the one or more functional domains in the pro-sequence of a polypeptide which contribute(s) to the folding of the inactive polypeptide into a biochemically active conformation.
