    The 1H-NMR study of diamagnetic cytochrome P450cam FeII-CO has been performed for the first time. Chemical shifts of the cysteinate fifth ligand protons and of several heme protons have been assigned through 1- and 2-dimensional spectra at 500 MHz. A substrate dependance has been observed for the resonance of the cysteinate proton detected in the high-field region.
