A method for the production of the N-terminal four kringle-containing fragment of hepatocyte growth factor (NK4) by expression of a nucleic acid encoding said NK4 in a microbial host cell, isolation of inclusion bodies containing said NK4 in denatured form, solubilization of the inclusion bodies and naturation of the denatured NK4, characterized in that solubilization and naturation are performed at pH 7-9 in phosphate buffered solution, provides NK4 in high purity and high yield.
