The serum amyloid P component (SAP) has been found to associate in vitro with a variety of polysaccharide and proteinaceous ligands including the yeast cell wall polysaccharide preparation, zymosan, in the presence of calcium at neutral pH. In the present study, we have investigated the role of copper and zinc and other divalent cations and acidic pH on the binding of SAP to zymosan. We report that binding occurs not only in the presence of calcium, but in the presence of copper, zinc, and… CONTINUE READING
