    • The invention concerns a polypeptide which has the activity of an inhibitor DE-3 from Erythrina caffra and reversibly and selectively binds serin proteases from a protein mixture, obtained by culturing prokaryotic or eukaryotic host cells transformed or transfected with a nucleic acid which codes for the polypeptide in question in such a way that the host cells, under favourable nutrient conditions, can express the polypeptide. The invention also concerns the isolation of the polypeptide. The polypeptide is characterised by having an amino acid sequence which is functionally analogous to SEQ ID NO:2, is in one region over 85 % homologous with the region of amino acids 39-139 of that sequence, has two disulphide bridges and begins N-terminally with SEQ ID NO:4 or with a SEQ ID NO:4 extended N terminally by methionin, has a binding capacity for tissue plasminogen activators of 1.25 MU/ml or more. The polypeptide in question is especially suitable for use in purifying plasminogen activators such as tissue plasminogen activators (t-PA and derivatives).
