CC   -!- FUNCTION: Part of a membrane-bound tetrathionate reductase that
CC       catalyzes the reduction of tetrathionate to thiosulfate. TtrC probably
CC       anchors TtrA and TtrB to the external face of the cytoplasmic membrane.
CC       May transfer electrons from membrane quinol to TtrB (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Probably composed of three subunits: TtrA, TtrB and TtrC.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the NrfD family. {ECO:0000305}.
