Binding activity was measured by competitive inhibition of 125I-lactosyl-bovine serum albumin binding to the immobilized lectins. With the solubilization procedure used extracts of vegetative cells and of early aggregates had no significant inhibitory activity, but an abundant discoidin-binding substance was detected in late aggregates and fruiting bodies. This material was purified by ethanol and acid precipitation followed by precipitation with discoidin. It is a polysaccharide composed of 77% galactose, 15% N-acetylgalactosamine, 5% glucose, and 3% N-acetylglucosamine and may be a biologically functional ligand for the slime mold lectins, in particular discoidin II. Use of axenic cells was critical in these experiments, since extracts of Escherichia coli and Klebsiella aerogenes, commonly used as food for D. discoideum, were found to contain substances that react with discoidin. This would complicate isolation of endogenous discoidin ligands from cells raised on bacteria."xsd:string |
