Protein

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

Gene

T20H4.5

Organism
Caenorhabditis elegans
Status
Reviewed - Annotation score: 4 out of 5- 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.

Cofactori

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