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:0000256|RuleBase:RU003403}. 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 Evidence={ECO:0000256|ARBA:ARBA00000766, CC ECO:0000256|RuleBase:RU003403}; CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000256|ARBA:ARBA00004141}; Multi- CC pass membrane protein {ECO:0000256|ARBA:ARBA00004141}. Mitochondrion CC inner membrane {ECO:0000256|ARBA:ARBA00004448, CC ECO:0000256|RuleBase:RU003403}; Multi-pass membrane protein CC {ECO:0000256|ARBA:ARBA00004448, ECO:0000256|RuleBase:RU003403}. CC -!- SIMILARITY: Belongs to the complex I subunit 2 family. CC {ECO:0000256|ARBA:ARBA00007012, ECO:0000256|RuleBase:RU003403}.
