![]() This output domain is coupled with the C-terminal signaling domain responding to a range of stimuli in the form of different small molecules. The proteins in the GntR family share a characteristic version of the N-terminal winged helix-turn-helix (wHTH) DNA-binding domain. This is true for the GntR family of transcriptional regulators, which gathers close to 2000 members in both bacterial and archael genomes ( Haydon and Guest 1991 Rigali et al. With extensive sequence similarity in the DNA-binding domain, these large families often contain proteins with different types of the effector domains fused to similar DNA-binding domains ( Rosinski and Atchley 1999 Perez-Rueda and Collado-Vides 2000). 1994), GntR ( Haydon and Guest 1991), and AraC ( Gallegos et al. Some of the largest such families ( Perez-Rueda et al. Based on sequence similarity, predominantly in the DNA binding domain one-component systems identified in sequenced genomes are assembled into protein families usually named after the best-characterized member. Signal transduction in prokaryotes is dominated by such systems, where small molecule-binding domains constitute the majority of the input domains and helix-turn-helix (HTH) DNA-binding domains are the most common output domains ( Ulrich et al. The structural comparison of the C-PhnF and UbiC proteins allows us to propose that a similar site in the PhnF structure is adapted for effector binding.Ī protein containing a sensor input domain and a functional output domain is described as a one-component system ( Ulrich et al. ![]() C-PhnF shares strong structural similarity with the chorismate lyase fold, which features a buried active site locked behind two helix-turn-helix loops. C-PhnF monomers form a dimer by establishing interdomain eight-strand β-sheets that include core antiparallel and N-terminal two-strand parallel β-sheets from each monomer. The structure represents a mixture of α-helices and β-strands, with a six-stranded antiparallel β-sheet at the core. The C-PhnF structure provides for the first time the scaffold of this domain for the HutC subfamily, which covers about 31% of GntR-like regulators. Members of this family share similar N-terminal DNA-binding domains, but are divided into four subfamilies according to their heterogenic C-terminal domains, which are involved in effector binding and oligomerization. The PhnF protein belongs to the HutC subfamily of the large GntR transcriptional regulator family.
