RESUMO
1. The proton NMR spectra of oxidised and reduced French bean plastocyanin have been recorded on a 270 MHz pulsed spctrometer. 2. The spectrum of a mixture containing the protein in the paramagnetic Cu(II) and diamagnetic Cu(I) states is a superposition of the separate spectra. When ferrirate spectra. 3. The results show that self-exchange between Cu(II)- and Cu(I)-plastocyanin is slow on the NMR time scale (kex less than 2-10(4) M-1-s-1 at 50 degrees C), and that electron transfer in the presence of ferricyanide is rapid (k greater than 1-10(5) M-1-s-1).
