Protein

NADH dehydrogenase [ubiquinone] iron-sulfur protein 8, mitochondrial

Gene

NDUFS8

Organism
Pan troglodytes (Chimpanzee)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

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).
NADH + acceptor = NAD+ + reduced acceptor.
