Lateral mobility of cytochrome c on intact mitochondrial membranes as determined by fluorescence redistribution after photobleaching.

RESUMO
Lateral mobility of an active fluorescent derivative of cytochrome c on the membranes of giant mitochondria was measured by fluorescence redistribution after photobleaching. A diffusion coefficient of 1.6 X 10(-10) cm2/sec was determined for the labeled cytochrome c on inner mitochondrial membranes under conditions where succinate oxidase activity was demonstrated. This relatively low rate of diffusion, together with results of other investigators, is explained in terms of a model involving a dynamic equilibrium between freely diffusing and associated forms of electron-transfer components.
