    摘要: Endothelin converting enzymes of human blood origin or human cells origin are disclosed, which have the following properties:

    (1) Action: being capable of converting big endothelin to endothelin;
    (2) Substrate specificity: acting on big endothelin-1, big endothelin-2, or big endothelin-3;
    (3) Optimum pH: pH 6.5-7.5;
    (4) Molecular weight: about 5.4 x 10⁵ as measured on gel-filtration using a column of crosslinked agarose gel bead (exclusion limit 5 x 10⁶ Daltons);
    (5) Inhibitors: inhibited by ethylenediaminetetraacetate (EDTA), phosphoramidon, thiorphan, phenylmethanesulfonyl fluoride (PMSF), and chymostatin;
    (6) Hydrated density: not greater than about 1.210 g/ml;
    (7) Formation of precipitate: precipitation by adding 0.65% dextran sulfate (M.W. 500,000) and 0.2 M manganese chloride;
    (8) Influence of oxidation: inactivated by oxidation by copper ion.
