CC ChEBI:CHEBI:83100; EC=1.8.1.4;
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692; Evidence={ECO:0000250};
CC Note=Binds 1 FAD per subunit. {ECO:0000250};
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}. Membrane; Peripheral
CC membrane protein.
CC -!- MISCELLANEOUS: The active site is a redox-active disulfide bond.
