Protein

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

Gene
N/A
Organism
Solanum tuberosum (Potato)
Status
Reviewed - Annotation score: 5 out of 5- 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). May donate electrons to ubiquinone.By similarity

Catalytic activityi

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

Cofactori

[4Fe-4S] clusterBy similarityNote: Binds 2 [4Fe-4S] clusters per subunit.By similarity
