Recombinant Escherichia coli HTH-type transcriptional repressor PurR(purR)

Product Type Recombinant Protein
Uniprot No. C4ZYC2
Species Escherichia coli (strain K12 / MC4100 / BW2952)
Gene Names purR
Protein Names Recommended name: HTH-type transcriptional repressor PurR Alternative name(s): Pur regulon repressor Purine nucleotide synthesis repressor
Storage The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Function Is the main repressor of the genes involved in the de novo synthesis of purine nucleotides, regulating purB, purC, purEK, purF, purHD, purL, purMN and guaBA expression. PurR is allosterically activated to bind its cognate DNA by binding the purine corepressors, hypoxanthine or guanine, thereby effecting transcription repression.
