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 during anaerobic growth,
CC       and succinate dehydrogenase is used during aerobic growth. The QFR
CC       enzyme complex binds 2 quinones in or near the membrane; 1 near the
CC       [3Fe-4S] cluster (QP is proximal to the [3Fe-4S] cluster, on the
CC       cytoplasmic side of the membrane) while QD (the distal cluster) is on
CC       the other side of the membrane. It is not clear if both of the quinol-
CC       binding sites are functionally relevant (PubMed:10373108,
CC       PubMed:11850430). {ECO:0000269|PubMed:10373108,
