| + | [[http://www.uniprot.org/uniprot/TETR4_ECOLX TETR4_ECOLX]] 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. | ||
