    The protein

    Catalyzed reaction/ biological activity

  • quinone + succinate --> quinol + fumarate (according to UniProt)
  • Protein family

  • succinate dehydrogenase/fumarate reductase iron-sulfur protein family (single member, according to UniProt)
  • [SW|Cofactors]

  • Fe-S cluster [pubmed|29292548]
  • Effectors of protein activity

  • Inhibited by 2-(n-Heptyl)-4-hydroxy-quinoline N-oxide [Pubmed|3910107]
