1.14.15.36 heme heme-iron reduction is the rate limiting step in catalysis. Protonation of the cysteinate ligand to the ferrous CYP51 underlies the collapse of the Fe(II)-CO adduct of the enzyme from its P450 to its P420 form. The protonation is reversible and the rate of P420 formation is substantially retarded in the estriol-bound form of CYP51 Mycobacterium tuberculosis
