title: The uniqueness of superoxide dismutase (SOD)--why cannot most copper compounds substitute SOD in vivo?
abstract: It is shown that the copper zinc superoxide dismutase is unique in its ability to catalyze O2- dismutation in vivo in contrast to other copper compounds which have this feature only in vitro. The reasons for this difference are discussed in terms of kinetic and thermodynamic parameters.
