Abstract：
:Heparin cofactor II (HCII) is a specific thrombin inhibitor; its inhibitory activity is stimulated by heparin (Hep) and dermatan sulfate (DS). Vitronectin (VN), a heparin binding adhesive glycoprotein present in plasma and extracellular matrix, has been shown to decrease the stimulatory effect of Hep but not of DS on thrombin inhibition by HCII (Preissner and Sié, 1988). We analyzed the effect of glycosaminoglycans (GAGs) and GAG-binding proteins on the HCII/thrombin interaction in more detail. HCII was purified from the supernatant of barium citrate adsorbed normal human plasma by polyethylene glycol precipitation followed by affinity chromatography on heparin-Sepharose CL-6B and ion-exchange chromatography on a QAE-Sephadex A-50. Inhibition of thrombin by HCII was studied in the absence and presence of GAGs (hep 0.03-30 micrograms/ml, DS 0.05-50 micrograms/ml, heparan sulfate (HS) 0.05-50 micrograms/ml) in a chromogenic substrate assay using S-2366 as a thrombin substrate. The effects of VN and fibronectin (FN) on HCII stimulation by GAGs were determined. In addition to Hep and DS the inhibitory effect of HCII was stimulated by HS, however, to a lesser extent. Using 0.03U/ml thrombin and 1nM HCII the stimulatory effect of GAGs was completely inhibited when Hep (less than or equal to 0.3 micrograms/ml) was preincubated with VN (60 micrograms/ml) and decreased to less than 50% when HS (50 micrograms/ml) was preincubated with VN (60 micrograms/ml). VN had no effect on DS as already described previously.(ABSTRACT TRUNCATED AT 250 WORDS)
