The electron paramagnetic resonance spectra of the heme domain of inducible nitric oxide synthase (iNOS) demonstrate a close relationship to the corresponding spectra of the neuronal isoform (nNOS). The binding of ligands to the iNOS arginine site perturbs the environment of the high-spin ferriheme in a highly ligand-specific manner. The iNOS forms five-coordinate, high-spin complexes with arginine analogs which are clearly related to the corresponding complexes of nNOS. Studies indicate that the binding of L-arginine, N(omega)-hydroxy-L-arginine (NHA), and N(omega)-methyl-L-arginine (NMA) produces various spectroscopic species closely corresponding to the equivalent complexes of nNOS, while N(omega)-nitro-L-arginine (NNA) binding produces a state which appears intermediate in character between the nNOS NNA and arginine complexes. These spectroscopic studies have permitted the determination of ligand-specific high-spin states which reveal similarities and differences between iNOS and nNOS.
