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). {ECO:0000256|ARBA:ARBA00025649}.
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000256|PIRSR:PIRSR000089-1};
CC Note=Binds 1 FAD per dimer. {ECO:0000256|PIRSR:PIRSR000089-1};
CC -!- SUBUNIT: Heterodimer of an alpha and a beta subunit.
CC {ECO:0000256|ARBA:ARBA00011355}.
CC -!- SIMILARITY: Belongs to the ETF alpha-subunit/FixB family.
CC {ECO:0000256|ARBA:ARBA00005817}.
