Dispersion of reactivity of copper proteins in solutions.
The redox reactions of superoxide dismutase and ceruloplasmin fit the simple kinetic schemes if the dispersion of their reactivities is accounted for by the time-dependent rate constants of the form k(t) = Bt alpha-1, 0 less than alpha less than or equal to 1. The lower the value of alpha the greater is the dispersion of reactivity. The limit of classical kinetics corresponds to alpha = 1.
