Abstract excerpt
Thr-303 to Lys-mutated P-450 2E1, as well as Thr-301 to Lys-mutated P-450 2C2, had absorption spectra characteristic of a nitrogenous ligand-bound form of P-450, such as the pyridine complex of P-450 2E1; (i) in the ferric state, the red-shifted Soret band, compared with the typical low-spin type spectrum of P-450, and the more intense beta band than the alpha band and (ii) in the ferrous state, two Soret peaks...
