NADH dehydrogenase [ubiquinone] 1 beta subcomplex subunit 5, mitochondrial
Function
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.
Sequence Similarities
Belongs to the complex I NDUFB5 subunit family.
