THESE OBSERVATIONS SUGGEST THAT THIS MAGNESIUM SITE MAY BE PARTIALLY OCCUPIED BY A HEAVIER META ION IN THE PROTEIN CRYSTAL. THERE ARE RESIDUAL DENSITIES IN (FO-FC) DIFFERENCE FOURIER MAP AT THE SITE OF CU AND HEMEA FE. THESE DENSITIES SUGGEST THAT THE METEAL CENTER OF THIS MUTATNT MIGHT BE IN A STATE DIFFERENT FROM WILD TYPE IN CRYSTAL.
