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 -!- SUBCELLULAR LOCATION: Mitochondrion membrane {ECO:0000250}; Multi-pass
CC membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the complex I subunit 4L family. {ECO:0000305}.
