CC -!- FUNCTION: The electron transfer flavoprotein serves as a specific
CC electron acceptor for other dehydrogenases. It transfers the electrons
CC to the main respiratory chain via ETF-ubiquinone oxidoreductase (ETF
CC dehydrogenase) (By similarity). {ECO:0000250}.
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692; Evidence={ECO:0000250};
CC Note=Binds 1 FAD per dimer. {ECO:0000250};
CC -!- COFACTOR:
CC Name=AMP; Xref=ChEBI:CHEBI:456215; Evidence={ECO:0000250};
CC Note=Binds 1 AMP per subunit. {ECO:0000250};
CC -!- SUBUNIT: Heterodimer of an alpha and a beta subunit.
CC -!- SIMILARITY: Belongs to the ETF beta-subunit/FixA family. {ECO:0000305}.
