Crystallographic cyanide-probing for cytochrome c oxidase reveals structural bases suggesting that a putative proton transfer H-pathway pumps protons

Cytochrome c oxidase (CcO) reduces O(2) in the O(2)-reduction site by sequential four-electron donations through the low-potential metal sites (Cu(A) and Fe(a)). Redox-coupled X-ray crystal structural changes have been identified at five distinct sites including Asp(51), Arg(438), Glu(198), the hydr...
