Protein

NADH dehydrogenase [ubiquinone] iron-sulfur protein 3

Gene

NAD9

Organism
Beta vulgaris (Sugar beet)
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.
