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).
CATALYTIC ACTIVITY: NADH + ubiquinone = NAD⁺ + ubiquinol.
CATALYTIC ACTIVITY: NADH + acceptor = NAD⁺ + reduced acceptor.
SUBUNIT: Complex I is composed of about 45 different subunits (By similarity).
SUBCELLULAR LOCATION: Mitochondrion inner membrane (By similarity).
SIMILARITY: Belongs to the complex I 30 kDa subunit family.
