N2 - Two new methods have been devised for measuring fumarate reduction by beef heart succinate-ubiquinone oxidoreductase with quinols as electron donors. In one assay the quinone is maintained in the reduced state by coupling fumarate reduction with the DT diaphorase reaction, in the other assay by the presence of excess dithionite. The advantages of these methods are discussed, along with preliminary characterization of the quinol-protein interaction.
