CC   -!- FUNCTION: Two distinct, membrane-bound, FAD-containing enzymes are
CC       responsible for the catalysis of fumarate and succinate
CC       interconversion; fumarate reductase is used in anaerobic growth, and
CC       succinate dehydrogenase is used in aerobic growth. Anchors the
CC       catalytic components of the fumarate reductase complex to the cell
CC       inner membrane, binds quinones. {ECO:0000255|HAMAP-Rule:MF_00708}.
CC   -!- SUBUNIT: Part of an enzyme complex containing four subunits: a
CC       flavoprotein (FrdA), an iron-sulfur protein (FrdB), and two hydrophobic
CC       anchor proteins (FrdC and FrdD). {ECO:0000255|HAMAP-Rule:MF_00708}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00708}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00708}.
CC   -!- SIMILARITY: Belongs to the FrdC family. {ECO:0000255|HAMAP-
CC       Rule:MF_00708}.
