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 ChEBI:CHEBI:57540, ChEBI:CHEBI:57945; EC=7.1.1.2;
CC -!- SUBUNIT: Complex I is composed of at least 49 different subunits.
CC -!- SUBCELLULAR LOCATION: Mitochondrion membrane {ECO:0000305}; Multi-pass
CC membrane protein {ECO:0000305}.

CC -!- MISCELLANEOUS: A stretch of 270 kb of the mitochondrial genome is
CC duplicated within the centromere of chromosome 2 resulting in the
CC duplication of the gene. The expression of the duplicated gene
CC (At2g07731) is not demonstrated. It is also probably not RNA edited and
CC therefore differs in all the positions known to be edited.
CC -!- SIMILARITY: Belongs to the complex I subunit 6 family. {ECO:0000305}.
