UniProtKB - Q34799 (NU2M_SYMSY)
Protein
NADH-ubiquinone oxidoreductase chain 2
Gene
MT-ND2
Organism
Symphalangus syndactylus (Siamang) (Hylobates syndactylus)
Status
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
