The rate of reaction between cytochrome C peroxidase and hydrogen peroxide is not diffusion limited.
The apparent biomolecular rate constant for the cytochrome C peroxidase (EC 1.11.1.5)-hydrogen peroxide reaction has been measured as a function of temperature between 5 and 25 degree C at pH 4,5.5, and 7 and as a function of viscosity over a fifteen-fold range. From the independence of the rate constant on the viscosity, it is concluded that the reaction is not diffusion limited.
