The properties of the heme, flavin mononucleotide (FMN) and FeS domains of P450 RhF, from Rhodococcus sp. NCIMB 9784, expressed separately and in combination are analysed. The nucleotide preference, imidazole binding and reduction potentials of the heme and FMN domains are unaltered by their separat...
