3H-FMLP, a chemotactic peptide that resembles Escherichia coli chemotactic factor, is chemotactic for PAM, binds specifically to a site on the cell, and induces the generation of superoxide radicals by the cell. Scatchard analysis revealed an equilibrium dissociation constant at 26 degrees C of 1.45 x 10(-8)M and the presence of 1.7 , 10(5) receptors per cell. Binding was not inhibited by a partially purified C5a preparation or by the neutrophil-derived CCF but was inhibited by various N-formylated peptides. The order of potency of each peptide to inhibit 3H-FMLP binding was identical to the order of potency of each peptide to induce generation of superoxide by the PAM. Only small amounts of beta-glucuronidase activity and no lysozyme were detected in the supernatant after incubation of the cells for 30 min with varying concentrations of FMLP.
