[1]	NUCLEOTIDE SEQUENCE [LARGE SCALE MRNA]. TISSUE=Testis; International consortium for macaque cDNA sequencing and analysis; "DNA sequences of macaque genes expressed in brain or testis and its evolutionary implications."; Submitted (JUN-2005) to the EMBL/GenBank/DDBJ databases.

Comments

FUNCTION: Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) that is believed to belong to the minimal assembly required for catalysis. Complex I functions in the transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone (By similarity). This is the largest subunit of complex I and it is a component of the iron-sulfur (IP) fragment of the enzyme. It may form part of the active site crevice where NADH is oxidized (By similarity).
CATALYTIC ACTIVITY: NADH + ubiquinone = NAD⁺ + ubiquinol.
CATALYTIC ACTIVITY: NADH + acceptor = NAD⁺ + reduced acceptor.
COFACTOR: Binds 1 2Fe-2S cluster per subunit (By similarity).
COFACTOR: Binds 2 4Fe-4S clusters per subunit (By similarity).
SUBUNIT: Complex I is composed of 45 different subunits (By similarity).
SUBCELLULAR LOCATION: Mitochondrion inner membrane (By similarity). Note=Matrix and cytoplasmic side of the mitochondrial inner membrane (By similarity).
SIMILARITY: Belongs to the complex I 75 kDa subunit family.
SIMILARITY: Contains 1 2Fe-2S ferredoxin-type domain.
