title: [Reaction capacity of the nonequilibrium form of cytochrome c formed during reduction of the protein by radicals].
abstract: It has been shown that during fast (< 1 ms) photosensitized by anthraquinone or benzophenone reduction of cytochrome c in 0.15 N NaOH water-glycerol solutions ferrocytochrome c in a nonequilibrium state with increased reactivity was formed. The rate constants for reactions of CO binding to nonequilibrium and equilibrium ferrocytochrome c are 2.10(4) M-1S-1 and 70 M-1S-1 correspondingly. Nonequilibrium cytochrome c is relaxed to corresponding equilibrium state with lambda = 4 S-1.
