title: Isolation, structural organization and mechanism of action of mitochondrial steroid hydroxylating systems.
abstract: A scheme for the isolation of individual proteins of the 20S,22R-cholesterol hydroxylating system is presented. Physico-chemical and structural parameters of cytochrome P-450 are furnished. Self-reconstitution of indivudal proteins of the system into an enzyme unit is shown. Furthermore a regulation process of electron transport in the 20S,22R-cholesterol system is considered.
