Identification
HMDB Protein ID HMDBP00159
Secondary Accession Numbers
  • 5391
  • HMDBP03482
Name NADH dehydrogenase [ubiquinone] 1 alpha subcomplex subunit 2
Synonyms
  1. CI-B8
  2. Complex I-B8
  3. NADH-ubiquinone oxidoreductase B8 subunit
Gene Name NDUFA2
Protein Type Enzyme
Biological Properties
General Function Involved in NADH dehydrogenase (ubiquinone) activity
Specific 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
