7673215-13	1995	Of the four amino acids tested at position 142, only arginine resulted in a decrease in cytochrome b reduction through center N. These findings are discussed in terms of the structure and function of the quinol oxidation site and seem to indicate that Trp-142 is not critical to the kinetic interaction of ubiquinol with the reductase, but plays an important role in the electron transfer reactions that intervene between ubiquinol oxidation and cytochrome c1 reduction.
