Protein

NADH-ubiquinone oxidoreductase 49 kDa subunit

Gene

NAD7

Organism
Cafeteria roenbergensis (Marine flagellate)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

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). Component of the iron-sulfur (IP) fragment of the enzyme. Component of the iron-sulfur (IP) fragment of the enzyme (By similarity).By similarity

Catalytic activityi

NADH + ubiquinone + 5 H+(In) = NAD+ + ubiquinol + 4 H+(Out).
NADH + acceptor = NAD+ + reduced acceptor.
