Abstract:
DFT analysis of several models for 2,3,5-trimethylbenzoquinol oxidation in the catalytic center of the cytochrome b6f complex, consisting of the [Fe2S2] cluster and its surroundings, has been performed. The comparison of optimized structures with different numbers (14–20) of fixed internal coordinates allowed us to find an optimal model close to the crystal structure.
