title: Pulsed cytochrome c oxidase.
abstract: The identification of two functionally distinct states, called pulsed and resting, has led to a number of investigations on the conformational variants of the enzyme. However, the catalytic properties of cytochrome oxidase may depend on a number of experimental conditions related to the solvent as well as to the protocol followed to determine the turnover number of the enzyme. This paper reports results which illustrate that the steady-state differences between pulsed and resting oxidase may, or may not, be detected depending on experimental conditions.
