1061127-5	1976	The infrared stretching frequencies of ferrous porphyrin carbonyl complexes and the absorption spectrum of the CO adduct of Na[Fe1(meso-tetraphenylporphyrin dianion)] are consistent with the concept that in P-450 considerable electron density is transferred to the iron by the mercaptide ligand.	Porphyrins	47-56	cytochrome P450 family 2 subfamily B member 6	Homo sapiens	207-212	
19185039-1	2009	Two new models for cytochrome P450 in which the thiolate axial ligand is replaced by a RSO(3)(-) group, form oxo-iron(IV) porphyrin pi-cation radicals as sole oxidation products in "peroxo shunt" reactions independent of the nature of the employed solvent (polar or non-polar) and electronic nature of the porphyrin rings.
