FADR, FATTY ACID RESPONSIVE TRANSCRIPTION FACTOR FROM E. COLIFADR, FATTY ACID RESPONSIVE TRANSCRIPTION FACTOR FROM E. COLI

Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedFadR 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. Crystal structure of FadR, a fatty acid-responsive transcription factor with a novel acyl coenzyme A-binding fold.,van Aalten DM, DiRusso CC, Knudsen J, Wierenga RK EMBO J. 2000 Oct 2;19(19):5167-77.
