Collection of regulogs for PurR transcription factor

PurR is a repressor belonging to the LacI family. PurR was experimentally analyzed in Escherichia coli. In the presence of effectors, hypoxanthine or guanine, PurR protein dimer binds to its palindromic operators. The PurR regulon includes genes involved in the biosynthesis of purine and pyrimidine nucleotides. We used a comparative genomics approach to reconstruct transcriptional regulons controlled by PurR orthologs in Gammaproteobacteria [12391881].
