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 -!- SUBUNIT: Heterodimer of an alpha and a beta subunit. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix {ECO:0000250}.
CC -!- MISCELLANEOUS: Present with 2950 molecules/cell in log phase SD medium.
CC {ECO:0000269|PubMed:14562106}.
CC -!- SIMILARITY: Belongs to the ETF alpha-subunit/FixB family.
CC {ECO:0000305}.
