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.
CC   -!- RNA EDITING: Modified_positions=5 {ECO:0000269|PubMed:8528607}, 31
CC       {ECO:0000269|PubMed:8528607}, 38 {ECO:0000269|PubMed:8528607}, 56
