NADH dehydrogenase [ubiquinone] 1 beta subcomplex subunit 2 mitochondrial is an enzyme that in humans is encoded by the NDUFB2 gene.The protein encoded by this gene is a subunit of the multisubunit NADH:ubiquinone oxidoreductase (complex I). Mammalian complex I is composed of 45 different subunits. This protein has NADH dehydrogenase activity and oxidoreductase activity. It plays an important role in transferring electrons from NADH to the respiratory chain.
