Unspecific protease inhibitor highly similar to EDTA. Inhibition results from chelating of calcium and magnesium ions leading to their removal from the surrounding medium. However, affinity to calcium2+ is much higher than that to magnesium2+. The inhibitory effect can be compensated by an excess of calcium2+ or magnesium2+. pKa calcium (pH 7): approx. 6.9
