Decoupling mutations in the D-channel of the aa(3)-type cytochrome c oxidase from Rhodobacter sphaeroides suggest that a continuous hydrogen-bonded chain of waters is essential for proton pumping
The aa(3)-type cytochrome c oxidase from Rhodobacter sphaeroides utilizes two proton-input channels to provide all the protons for chemistry (water formation) and proton pumping. The D-channel is responsible for the uptake of all pumped protons, 4 protons per O(2). Several substitutions for either N...
