A low molecular weight serine protease inhibitor (TAP) was purified from extracts of the soft tick, Ornithodoros moubata. The peptide is a slow, tight-binding inhibitor, specific for factor Xa (Ki = 0.588 +/- 0.054 nM). The inhibitor also acts as an anticoagulant in several human plasma clotting assays in vitro. Its amino acid sequence (60 residues) has limited homology to the Kunitz-type inhibitors. However, unlike other inhibitors of this class, TAP inhibits only factor Xa. It had no effect at a 300-fold molar excess on factor VIIa, kallikrein, trypsin, chymotrypsin, thrombin, urokinase, plasmin, tissue plasminogen activator, elastase, or Staphylococcus aureus V8 protease. TAP's specificity and size suggest that it may have therapeutic value as an anticoagulant.

Correlative interconnections between plasminogen activator (PA) activity (fibrin plate method) and level of urokinase antigen (Ag UAP) and tissue PA antigen (Ag TAP) in urine and blood (ELISA) were studied in 60 patients with chronic glomerulonephritis (CGN) and 38 patients with amyloidosis. The high degree of positive correlation between blood and urine initial PA activity and Ag UAP content was found. This suggests the possible leading role of UAP in formation of the basal fluctuations of fibrinolytic activity in blood and urine. High degree of correlation--r = +0.84 and p < 0.001--was found between blood Ag UAP and urine Ag TAP in amyloidosis only. The functional protein loading probe revealed great importance of high urine and blood AP activity in realizing of ultrafiltration renal process--in CGN and amyloidosis.
