[Identity of kininogenase and plasminogen activators in human granulocytes].
It was shown that the plasminogen activator inhibitor, ZGlyGlyArgCH2Cl, inactivates the kininogenase and plasminogen activator activities in the whole human granulocyte lysate and human granulocyte proteinase fractions isolated by isoelectrofocusing from the granulocyte lysate (pH 3-10). The kinetics of irreversible inhibition of the ZGlyGlyArgpNA-amidase activity in granulocyte proteinase fractions (pI 10.75, 8.9 and 8.3) by ZGlyGlyArgCH2Cl was measured. These data confirm the earlier obtained results on the trypsin-like nature of the human granulocyte plasminogen activator and its identity to this cell kininogenase.
