Identification
HMDB Protein ID CDBP00167
Secondary Accession Numbers Not Available
Name NADH dehydrogenase [ubiquinone] 1 beta subcomplex subunit 3
Description Not Available
Synonyms
  1. CI-B12
  2. Complex I-B12
  3. NADH-ubiquinone oxidoreductase B12 subunit
Gene Name NDUFB3
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
