Identification
NameNADH-cytochrome b5 reductase 2
Synonyms
  • Mitochondrial cytochrome b reductase
  • p34/p32
  • NADH-cytochrome b5 reductase p34 form
  • NADH-cytochrome b5 reductase p32 form
Gene NameMCR1
Enzyme Class
Biological Properties
General FunctionInvolved in oxidoreductase activity
Specific FunctionThe 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
Cellular LocationNADH-cytochrome b5 reductase p34 form:Mitochondrion outer membrane; Single-pass membrane protein
