Protein attributes

Sequence length	588 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Two distinct, membrane-bound, FAD-containing enzymes are responsible for the catalysis of fumarate and succinate interconversion; the fumarate reductase is used in anaerobic growth, and the succinate dehydrogenase is used in aerobic growth.
Catalytic activity	Succinate + acceptor = fumarate + reduced acceptor.
Enzyme regulation	Inhibited by oxaloacetate.
Pathway	Carbohydrate metabolism; tricarboxylic acid cycle.
Subunit structure	Part of an enzyme complex containing four subunits: a flavoprotein, an iron-sulfur, cytochrome b-556, and an hydrophobic anchor protein. The complex forms trimers.
Subcellular location	Cell inner membrane; Peripheral membrane protein; Cytoplasmic side.
Sequence similarities	Belongs to the FAD-dependent oxidoreductase 2 family. FRD/SDH subfamily.
