CC   -!- FUNCTION: Core subunit of the mitochondrial membrane respiratory chain
CC       NADH dehydrogenase (Complex I) which catalyzes electron transfer from
CC       NADH through the respiratory chain, using ubiquinone as an electron
CC       acceptor. Essential for the catalytic activity of complex I.
CC       {ECO:0000250|UniProtKB:O75251}.
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         COMP:9566, ChEBI:CHEBI:15378, ChEBI:CHEBI:16389, ChEBI:CHEBI:17976,
CC         ChEBI:CHEBI:57540, ChEBI:CHEBI:57945; EC=7.1.1.2;
CC         Evidence={ECO:0000250|UniProtKB:O75251};
CC   -!- COFACTOR:
CC       Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Evidence={ECO:0000305};
CC       Note=Binds 1 [4Fe-4S] cluster. {ECO:0000305};
CC   -!- SUBUNIT: Core subunit of respiratory chain NADH dehydrogenase (Complex
CC       I) which is composed of 45 different subunits (By similarity). This is
CC       a component of the iron-sulfur (IP) fragment of the enzyme (By
CC       similarity). {ECO:0000250|UniProtKB:P42026}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC       {ECO:0000250|UniProtKB:P42026}; Peripheral membrane protein
CC       {ECO:0000250|UniProtKB:P42026}; Matrix side
CC       {ECO:0000250|UniProtKB:P42026}.
CC   -!- PTM: Hydroxylated ar Arg-111 by NDUFAF5 early in the pathway of
CC       assembly of complex I, before the formation of the juncture between
CC       peripheral and membrane arms. {ECO:0000250|UniProtKB:O75251}.
CC   -!- SIMILARITY: Belongs to the complex I 20 kDa subunit family.
CC       {ECO:0000305}.
