Oxygen kinetics of frozen cytochrome oxidase. The capacity of the oxygen pocket.

K De Fonseka, B Chance.   

Abstract

Low-temperature kinetics of the reaction between O2 and cytochrome oxidase suggest the existence of an O2 pocket of limited capacity in membrane-bound cytochrome oxidase, and one of larger capacity in purified cytochrome oxidase. A model is proposed to explain the difference in capacity of the pockets.
