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.
CC {ECO:0000250|UniProtKB:P03887}.
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 Evidence={ECO:0000250|UniProtKB:P03887};
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000250|UniProtKB:P03887}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:P03887}.
CC -!- SIMILARITY: Belongs to the complex I subunit 1 family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=X54252; Type=Erroneous termination; Note=Truncated C-terminus.; Evidence={ECO:0000305};
