Protein

NADH-ubiquinone oxidoreductase chain 4

Gene

ND4

Organism
Branchiostoma lanceolatum (Common lancelet) (Amphioxus lanceolatum)
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).By similarity

Catalytic activityi

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