CC   -!- FUNCTION: Anchors the catalytic components of the fumarate reductase
CC       complex to the cell membrane, binds quinones. {ECO:0000255|HAMAP-
CC       Rule:MF_00709}.
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_00709}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00709}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00709}.
CC   -!- SIMILARITY: Belongs to the FrdD family. {ECO:0000255|HAMAP-
CC       Rule:MF_00709}.
