RT   respiratory chain from the inner mitochondrial membrane of Solanum

CC   -!- FUNCTION: Accessory subunit of the mitochondrial membrane respiratory
CC       chain NADH dehydrogenase (Complex I), that is believed not to be
CC       involved in catalysis. Complex I functions in the transfer of electrons
CC       from NADH to the respiratory chain. The immediate electron acceptor for
CC       the enzyme is believed to be ubiquinone.
CC   -!- COFACTOR:
CC       Name=FAD; Xref=ChEBI:CHEBI:57692; Evidence={ECO:0000250};
CC       Note=Binds 1 FAD per subunit. {ECO:0000250};
CC   -!- SUBUNIT: Complex I is composed of about 45 different subunits.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion matrix.
CC   -!- SIMILARITY: Belongs to the complex I NDUFA9 subunit family.
CC       {ECO:0000305}.
