RT   "Nucleotide sequence of a cDNA clone from broccoli with high identity with
RT   the PSST subunit of NADH:ubiquinone oxidoreductase.";
RL   Plant Physiol. 108:859-860(1995).
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 (By
CC       similarity). {ECO:0000250}.
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   -!- COFACTOR:
CC       Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Evidence={ECO:0000305};
CC       Note=Binds 1 [4Fe-4S] cluster. {ECO:0000305};
CC   -!- SUBUNIT: Complex I is composed of about 45 different subunits. This is
CC       a component of the iron-sulfur (IP) fragment of the enzyme (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion.
CC   -!- SIMILARITY: Belongs to the complex I 20 kDa subunit family.
CC       {ECO:0000305}.
