Protein

NADH-ubiquinone oxidoreductase 49 kDa subunit

Gene

nad7

Organism
Dictyostelium discoideum (Slime mold)
Status
Reviewed-Annotation score: -Experimental evidence at protein 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

Catalytic activityi

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