Identification
Name:Formate dehydrogenase-O iron-sulfur subunit
Synonyms:
  • Aerobic formate dehydrogenase iron-sulfur subunit
  • FDH-Z subunit beta
  • Formate dehydrogenase-O subunit beta
Gene Name:fdoH
Enzyme Class:Not Available
Biological Properties
General Function:Involved in electron carrier activity
Specific Function:Allows to use formate as major electron donor during aerobic respiration. The beta chain is an electron transfer unit containing 4 cysteine clusters involved in the formation of iron- sulfur centers. Electrons are transferred from the gamma chain to the molybdenum cofactor of the alpha subunit
Cellular Location:Cell membrane; Single-pass membrane protein
