Oleic acid binds in a saturable fashion to human plasma fibronectin (FN). Analysis of the binding indicated the presence of a high affinity binding site with nKa approximately equal to 10 uM-1. Furthermore, it was found that binding of sodium oleate to FN modulated its susceptibility to degradation by various proteinases. FN saturated with sodium oleate was hydrolysed at a higher rate by trypsin, cathepsin D, thermolysin and pancreatic elastase than native FN. In contrast, sodium oleate inhibits the activity of two human granulocyte proteinases, human leucocyte elastase (HLE) and cathepsin G on either FN or on their respective specific synthetic substrates (at concentrations ranging from 10(-6) mM to 10 mM). Cathepsin G inhibition was non-competitive and gave a Ki in the 10 uM range similar to the previously reported inhibitory constant of oleic acid toward HLE.
