Zusammenfassung:In order to recombinantly prepare a biologically active protein of the TGF-beta superfamily, a protein, whose amino terminus consists of the pro sequence of a protein of the TGF-beta superfamily, or parts thereof, to which the mature domain of this protein or of another protein of TGF-beta superfamily which exhibits at least 35% homology with mature BMP-2 is attached, is expressed in prokaryotes under conditions in which at least a part of the protein is obtained in the form of inclusion bodies, the inclusion bodies are isolated and solubilized under denaturing conditions, the denatured, monomeric and biologically inactive protein which has been solubilized from the inclusion bodies is renatured, with folding and dimerization to give the soluble, biologically active conformation and, where appropriate, after the renaturation, the mature protein is released proteolytically from its pro form.
