Enzymes

General function:
Involved in oxidoreductase activity
Specific 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
