The ubiquinol-cytochrome C reductase complex (cytochrome bc1 complex) is an essential component of the mitochondrial cellular respiratory chain. This family represents the 6.4kD protein, which may be closely linked to the iron-sulphur protein in the complex and function as an iron-sulphur protein binding factor [1].	Domain
