NADH_B2

NADH_B2
PFAM accession number:PF14813
Interpro abstract (IPR026627):

NADH dehydrogenase [ubiquinone] 1 beta subcomplex subunit 2 is an 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 [ (PUBMED:12611891) (PUBMED:9878551) ].

GO component:mitochondrial respiratory chain complex I (GO:0005747), mitochondrial inner membrane (GO:0005743)
