Abstract: The effect of Val162 mutation(potentially relative to cancer) on cytochrome coxidase soluble Cu Adomain was studied by site-directed mutagenesis technique combined with UV-Vis, CD, fluorescence spectra, EPR and rapid kinetic methods.It is found that the mutation at the Val162site leads to a structural transformation and decreasing electron transfer activity.It provides important information for understanding the pathological mechanism.

Key words: Cytochrome coxidase, Site-directed mutation and diseases, Structure transformation, Electron transfer
