R. Soc. B 268:939-945(2001). CC -!- FUNCTION: Core subunit of the mitochondrial membrane respiratory CC chain NADH dehydrogenase (Complex I) that is believed to belong to CC the minimal assembly required for catalysis. Complex I functions CC in the transfer of electrons from NADH to the respiratory chain. CC The immediate electron acceptor for the enzyme is believed to be CC ubiquinone. {ECO:0000256|RuleBase:RU003640, CC ECO:0000256|SAAS:SAAS01013641}. CC -!- CATALYTIC ACTIVITY: CC Reaction=a ubiquinone + 5 H(+)(in) + NADH = a ubiquinol + 4 CC H(+)(out) + NAD(+); Xref=Rhea:RHEA:29091, Rhea:RHEA-COMP:9565, CC Rhea:RHEA-COMP:9566, ChEBI:CHEBI:15378, ChEBI:CHEBI:16389, CC ChEBI:CHEBI:17976, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945; CC EC=7.1.1.2; Evidence={ECO:0000256|RuleBase:RU003640, CC ECO:0000256|SAAS:SAAS01115044}; CC -!- SUBCELLULAR LOCATION: Mitochondrion membrane CC {ECO:0000256|SAAS:SAAS01013624}; Multi-pass membrane protein CC {ECO:0000256|SAAS:SAAS01013624}. CC -!- SIMILARITY: Belongs to the complex I subunit 3 family. CC {ECO:0000256|RuleBase:RU003640}.
