CC   -!- FUNCTION: Core subunit of the mitochondrial membrane respiratory
CC       chain NADH dehydrogenase (Complex I) that is believed to belong to
CC       the minimal assembly required for catalysis. Complex I functions
CC       in the transfer of electrons from NADH to the respiratory chain.
CC       The immediate electron acceptor for the enzyme is believed to be
CC       ubiquinone (By similarity).
CC   -!- CATALYTIC ACTIVITY: NADH + ubiquinone = NAD(+) + ubiquinol.
CC   -!- CATALYTIC ACTIVITY: NADH + acceptor = NAD(+) + reduced acceptor.
CC   -!- SUBUNIT: Complex I is composed of about 30 different subunits.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane (By
CC       similarity).
CC   -!- SIMILARITY: Belongs to the complex I 30 kDa subunit family.
