Protein
NADH-cytochrome b5 reductase 2
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
The outer membrane form may mediate the reduction of outer membrane cytochrome b5, and the soluble inter-membrane space form may transfer electrons from external NADH to cytochrome c, thereby mediating an antimycin-insensitive, energy-coupled oxidation of external NADH by yeast mitochondria. Involved in the reduction of D-erythroascorbyl free radicals.
Similarity
Belongs to the flavoprotein pyridine nucleotide cytochrome reductase family.
