== Function ==
[https://www.uniprot.org/uniprot/FADR_ECOLI FADR_ECOLI] Multifunctional regulator of fatty acid metabolism. Represses transcription of at least eight genes required for fatty acid transport and beta-oxidation including fadA, fadB, fadD, fadL and fadE. Activates transcription of at least three genes required for unsaturated fatty acid biosynthesis: fabA, fabB and iclR, the gene encoding the transcriptional regulator of the aceBAK operon encoding the glyoxylate shunt enzymes. Binding of FadR is specifically inhibited by long chain fatty acyl-CoA compounds.

== Publication Abstract from PubMed ==
FadR is a dimeric acyl coenzyme A (acyl CoA)-binding protein and transcription factor that regulates the expression of genes encoding fatty acid biosynthetic and degrading enzymes in Escherichia coli. Here, the 2.0 A crystal structure of full-length FadR is described, determined using multi-wavelength anomalous dispersion. The structure reveals a dimer and a two-domain fold, with DNA-binding and acyl-CoA-binding sites located in an N-terminal and C-terminal domain, respectively. The N-terminal domain contains a winged helix-turn-helix prokaryotic DNA-binding fold. Comparison with known structures and analysis of mutagenesis data delineated the site of interaction with DNA. The C-terminal domain has a novel fold, consisting of a seven-helical bundle with a crossover topology. Careful analysis of the structure, together with mutational and biophysical data, revealed a putative hydrophobic acyl-CoA-binding site, buried in the core of the seven-helical bundle. This structure aids in understanding FadR function at a molecular level, provides the first structural scaffold for the large GntR family of transcription factors, which are keys in the control of metabolism in bacterial pathogens, and could thus be a possible target for novel chemotherapeutic agents.
