>cd06275 PBP1_PurR Ligand-binding domain of purine repressor, PurR, which functions as the master regulatory protein of de novo purine nucleotide biosynthesis in Escherichia coli. Ligand-binding domain of purine repressor, PurR, which functions as the master regulatory protein of de novo purine nucleotide biosynthesis in Escherichia coli. This dimeric PurR belongs to the LacI-GalR family of transcription regulators and is activated to bind to DNA operator sites by initially binding either of high affinity corepressors, hypoxanthine or guanine. PurR is composed of two functional domains: aan N-terminal HTH (helix-turn-helix) domain, which is responsible for the DNA-binding specificity, and a C-terminal ligand-binding domain, which is homologous to the sugar-binding domain of ABC-type transport systems that contain the type I periplasmic binding protein-like fold. As also observed in the periplasmic binding proteins, the C-terminal domain of the purine transcription repressor undergoes a
