TetR5 Protein, E. coli, Recombinant (His)

TetR is the repressor of the tetracycline resistance element; its N-terminal region forms a helix-turn-helix structure and binds DNA. Binding of tetracycline to TetR reduces the repressor affinity for the tetracycline resistance gene (tetA) promoter operator sites. TetR5 Protein, E. coli, Recombinant (His) is expressed in E. coli expression system with N-6xHis tag. The predicted molecular weight is 27.7 kDa and the accession number is P21337.
