EPR spectra of native, immunoprecipitated CAO after wash with 0.1 mM EDTA. (A), CAO from Arabidopsis; 4 scans; 5 K; (B), CAO from Chlamydomonas; 2 scans; 5 K; (C), sample from Chlamydomonas treated as in (A) but with preimmune serum; 2 scans; 10 K. The shape of the weak spectrum in the preimmune control was out of phase with the g = 2.057 signal and thus did not contribute significantly to the spectrum of CAO. Microwave power was 2 mW. The y-axis was the same for all spectra.
