Abstract

The magnetic susceptibility of singly reduced, camphor-complexed cytochrome P-450 from Pseudomonas putida has been measured at various temperatures. Computer analysis using a spin Hamiltonian gives values of D between 15K and 25K, which agrees with a value of D = 20K found by low-field variable temperature Mössbauer spectroscopy. This result is compared with those from deoxyhemoglobin and deoxy-myoglobin.
