CC -!- FUNCTION: Core subunit of the mitochondrial membrane respiratory chain
CC NADH dehydrogenase (Complex I) that is believed to belong to the
CC minimal assembly required for catalysis. Complex I functions in the
CC transfer of electrons from NADH to the respiratory chain. The immediate
CC electron acceptor for the enzyme is believed to be ubiquinone. This is
CC the largest subunit of complex I and it is a component of the iron-
CC sulfur (IP) fragment of the enzyme. It may form part of the active site
CC crevice where NADH is oxidized.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a ubiquinone + 5 H(+)(in) + NADH = a ubiquinol + 4 H(+)(out) +
CC NAD(+); Xref=Rhea:RHEA:29091, Rhea:RHEA-COMP:9565, Rhea:RHEA-

CC ChEBI:CHEBI:57540, ChEBI:CHEBI:57945; EC=7.1.1.2;
CC -!- COFACTOR:
CC Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135; Evidence={ECO:0000250};
CC Note=Binds 1 [2Fe-2S] cluster per subunit. {ECO:0000250};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Evidence={ECO:0000250};
CC Note=Binds 2 [4Fe-4S] clusters per subunit. {ECO:0000250};
CC -!- SUBUNIT: Complex I is composed of about 40 different subunits.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane.
CC -!- SIMILARITY: Belongs to the complex I 75 kDa subunit family.
CC {ECO:0000305}.
