ArgR DNA-binding transcriptional dual regulator

Synonyms: ArgR, ArgR-L-arginine
Summary:
ArgR complexed with L-arginine represses the transcription of several genes involved in biosynthesis and transport of arginine, transport of histidine, and its own synthesis [2, 3, 4]and activates genes for arginine catabolism [12] ArgR is also essential for a site-specific recombination reaction that resolves plasmid ColE1 multimers to monomers and is necessary for plasmid stability [17]The role of ArgR in this latter reaction may be structural [17]br>The hexamer is the active form of ArgR, and L-arginine binds to ArgR and stabilizes the hexamer [18]nd increases its DNA affinity by allosteric activation [18, 19].
ArgR belongs to the ArgR/AhrC family, whose members are widely distributed in bacteria [5] The DNA sequence which the proteins of the family recognize and to which they bind are also well-conserved among genomes [5] This DNA sequence consists of a palindromic sequence of 18 bp, called the ARG box [4, 5] An ArgR hexamer binds to a pair of these boxes that are generally separated by 3 bp [4, 8] The repressor can bind to a single box but with a greatly reduced affinity [4, 8] The ARG box generally overlaps the promoter sequence and the transcriptional start site [4] therefore, it was suggested that it represses the transcription by steric exclusion of RNA polymerase binding [11]
ArgR has two domains: the N-terminal domain, which contains a winged helix-turn-helix DNA-binding motif [20] and the C-terminal domain, which contains a motif that binds L-arginine and a motif for oligomerization [18] Based on cross-linking analysis of wild-type and mutant ArgR proteins, it has been shown that the C-terminus is more important in cer/Xer site-specific recombination than in DNA binding [21]
