Jr, Engberg S.E., Lei R., Geng H., Sommer J.A., RA Randriamampionona R., Randriamanana J.C., Zaonarivelo J.R., RA Andriantompohavana R., Randria G., Prosper, Ramaromilanto B., RA Rakotoarisoa G., Rooney A., Brenneman R.A.; RT "Molecular and morphological analyses of the sportive lemurs (Family RT Megaladapidae: Genus Lepilemur) reveals 11 previously unrecognized RT species."; RL Spec. Publ. Mus. Tex. Tech. Univ. 49:1-47(2006). 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|SAAS:SAAS00136983}. CC -!- CATALYTIC ACTIVITY: NADH + ubiquinone + 5 H(+)(In) = NAD(+) + CC ubiquinol + 4 H(+)(Out). {ECO:0000256|RuleBase:RU003640, CC ECO:0000256|SAAS:SAAS00410250}. CC -!- SUBCELLULAR LOCATION: Mitochondrion membrane CC {ECO:0000256|SAAS:SAAS00410259}; Multi-pass membrane protein CC {ECO:0000256|SAAS:SAAS00410259}. CC -!- SIMILARITY: Belongs to the complex I subunit 3 family. CC {ECO:0000256|RuleBase:RU003640}.
