RT   "The sugar beet mitochondrial genome contains an ORF sharing sequence
RT   homology with the gene for the 30 kDa subunit of bovine mitochondrial
RT   complex I.";
RL   Mol. Gen. Genet. 241:479-481(1993).
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   -!- 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 inner membrane; Peripheral membrane
CC       protein; Matrix side.
CC   -!- RNA EDITING: Modified_positions=31 {ECO:0000269|PubMed:8246903}, 38
CC       {ECO:0000269|PubMed:8246903}, 100 {ECO:0000269|PubMed:8246903}, 110
CC       {ECO:0000269|PubMed:8246903}, 123 {ECO:0000269|PubMed:8246903};
CC   -!- SIMILARITY: Belongs to the complex I 30 kDa subunit family.
CC       {ECO:0000305}.
