Dissociation Rate Constants

The reaction of Neurospora crassa cytochrome c oxidase with CO was studied by flash-photolysis and rapid-mixing experiments, leading to the determination of the association and dissociation rate constants (7 X 10(4) M-1 X s-1 and 0.02s-1 respectively). Pre-steady-state kinetic investigations of the catalytic properties of the enzyme showed that under proper conditions Neurospora cytochrome c oxidase can be ‘pulsed’, i.e. activated, like the mammalian enzyme. The ‘pulsed’ species is spectroscopically different from the ‘resting’ one, and the decay into the ‘resting’ state is fast (t1/2 approx. 3 min).
