>cd03499 SQR_TypeC_SdhC Succinate:quinone oxidoreductase (SQR) Type C subfamily, Succinate dehydrogenase C (SdhC) subunit; composed of bacterial SdhC and eukaryotic large cytochrome b binding (CybL) proteins. SQR catalyzes the oxidation of succinate to fumarate coupled to the reduction of quinone to quinol. Members of this family reduce high potential quinones such as ubiquinone. SQR is also called succinate dehydrogenase or Complex II, and is part of the citric acid cycle and the aerobic respiratory chain. SQR is composed of a flavoprotein catalytic subunit, an iron-sulfur protein and one or two hydrophobic transmembrane subunits. Proteins in this subfamily are classified as Type C SQRs because they contain two transmembrane subunits and one heme group. The heme and quinone binding sites reside in the transmembrane subunits. The SdhC or CybL protein is one of the two transmembrane subunits of bacterial and eukaryotic SQRs. The two-electron oxidation of succinate in the flavoprotein a
