CC   -!- FUNCTION: The electron transfer flavoprotein serves as a specific
CC       electron acceptor for several dehydrogenases, including five acyl-CoA
CC       dehydrogenases, glutaryl-CoA and sarcosine dehydrogenase. It transfers
CC       the electrons to the main mitochondrial respiratory chain via ETF-
CC       ubiquinone oxidoreductase (ETF dehydrogenase) (By similarity).
CC       {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. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion matrix {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the ETF beta-subunit/FixA family. {ECO:0000305}.
