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).
CC {ECO:0000256|PIRNR:PIRNR000090}.
CC -!- SUBUNIT: Heterodimer of an alpha and a beta subunit.
CC {ECO:0000256|PIRNR:PIRNR000090}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix
CC {ECO:0000256|PIRNR:PIRNR000090}.
CC -!- SIMILARITY: Belongs to the ETF beta-subunit/FixA family.
CC {ECO:0000256|ARBA:ARBA00007557, ECO:0000256|PIRNR:PIRNR000090}.
