Expression and regulation
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.
- Operon:
fapR operon is under the control of SigA and FapR
