Puzzling subunits of mitochondrial cytochrome reductase.
In: Trends in Biochemical Sciences, Vol. 15, No. 5: pp. 178-180
The ubiquinol-cytochrome c reductase complex, like the other proton-pumping respiratory complexes of mitochondria, is an assembly of many different subunits. However, only a few of these subunits participate directly in the electron transfer and proton translocation. The roles of the other subunits are largely unknown. We discuss here some intriguing features of two of these subunits.
