Database entries

  • DBTBS entry: [1]
  • SubtiList entry: [2]

Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity: FapR regulates the expression of at least 10 genes (the fap regulon). It autoregulates its own expression. Malonyl-CoA, a precursor of fatty acid biosynthesis, binds to FapR changing its conformation to a non-DNA binding state. Hence, conditions that cause malonyl-CoA accumulation, like fatty acid biosynthesis inhibition, derepress the fap regulon.
  • Protein family: fapR family (according to Swiss-Prot)
  • Paralogous protein(s):
