The Currents of Life: The Terminal Electron-Transfer Complex of Respiration

A study on the crystal structure of a quinol oxidase fragment containing an engineered copper center is discussed as it relates to the electron transfer complex of respiration. One important finding in the structure of bacterial oxidase is the probable location of two proton channels.
