The multicopper proteins, nitrous-oxide reductase (N2OR) and cytochrome c oxidase (COX), were investigated by EPR spectroscopy at microwave frequencies 2.4-35 GHz. Our results support a Cu-Cu interaction in COX and N2OR. At least 10 lines in the 2.7-GHz, 12 lines in the 4.6-GHz and 14 lines in the 9.2 GHz spectra were resolved for N2OR. Eight copper lines at 2.7 GHz, about nine lines at 4.6 GHz and about six lines at 9.2 GHz were resolved for COX. Simulations of the EPR spectra were consistent… Expand
