Evolutionary conservation, predicted membrane topography of the subunits, and known chemical and physical properties of the catalytic metals in cytochrome oxidase provided the basis for plausible structural models of the enzyme's redox centres. Subunit II probably binds one of the copper ions (CuA) whilst subunit I is likely to bind the two haems (a and a3) and the other redox-active copper (CuB). Two cysteine and two histidine residues of subunit II are the likely ligands of CuA, forming a… CONTINUE READING
