NADH dehydrogenase [ubiquinone] 1 beta subcomplex subunit 1 (NDUFB1)

Accessory subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) that is believed to not participate in catalysis. Sophisticated I works in the transport of electrons from NADH to the respiratory chain.

The immediate electron acceptor for the enzyme is believed to be ubiquinone. .
