Type I copper proteins, plastocyanin and rice blue protein, were reduced with O_2^-. The reduction rate constants of plastocyanins from several sources with O_2^- are about 10^6 M^<-1> sec^<-1> (1.0 × 10^6 M^<-1> sec^<-1> for spinach and kidney bean plastocyanins and 6.7 × 10^5 M^<-1>sec^<-1> for Japanese radish plastocyanin) at pH 7.8 at 25℃ and not significantly different from that observed for rice blue protein (7.3 × 10^5 M^<-1>sec^<-1>). Reduced plastocyanin was oxidized by H_2O_2 through the peroxidase-like reaction of Cu,Zn-superoxide dismutase.
