title: The affinity of cytochrome P-450 for ethyl isocyanide: an explanation of double soret spectra.
abstract: The 2 pH dependent peaks formed in the Soret region by the treatment of reduced hepatic microsomes or purified cytochrome P-448 with ethyl isocyanide do not exhibit identical dependence on ethyl isocyanide concentration. This behavior and other facts regarding double Soret spectra can be explained by a simple expostulation involving lipophilic and corrdinate binding of pi-acceptor ligands.
