Protein

NADH dehydrogenase [ubiquinone] iron-sulfur protein 2, mitochondrial

Gene

NDUFS2

Organism
Pongo pygmaeus (Bornean orangutan)
Status
Reviewed-Annotation score: 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

Catalytic activityi

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

Cofactori

[4Fe-4S] clusterNote: Binds 1 [4Fe-4S] cluster.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
