UniProtKB - Q9SKC9 (NDUB7_ARATH)
Protein
NADH dehydrogenase [ubiquinone] 1 beta subcomplex subunit 7
Gene
At2g02050
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Functioni
Accessory subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I), that is believed not to be involved in 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
