OX NCBI_TaxID=1929474 {ECO:0000313|EMBL:BBB16292.1}; RN [1] {ECO:0000313|EMBL:BBB16292.1} RP NUCLEOTIDE SEQUENCE. RA Sultana Z., Asakura A., Kinjo S., Nozawa M., Nakano T., Ikeo K.; RT "Molecular phylogeny of ten intertidal hermit crabs of the genus RT Pagurus inferred from multiple mitochondrial genes, with special RT emphasis on the evolutionary relationship of Pagurus lanuginosus and RT Pagurus maculosus."; RL Genetica 0:0-0(2017). 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:RU003297}. 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:RU003297}; CC -!- SUBCELLULAR LOCATION: Mitochondrion membrane CC {ECO:0000256|RuleBase:RU003297}; Multi-pass membrane protein CC {ECO:0000256|RuleBase:RU003297}. CC -!- SIMILARITY: Belongs to the complex I subunit 4 family. CC {ECO:0000256|RuleBase:RU003297, ECO:0000256|SAAS:SAAS00707377}.
