 57-188 7.78e-54

QacR-like protein, C-terminal region; This family features the C-terminal region of a number of proteins that bear similarity to the QacR protein, a transcriptional regulator of the TetR family. QacR is able to bind various environmental agents, which include a number of cationic lipophilic compounds, and thus regulate the transcription of QacA, a multidrug efflux pump. The C-terminal region contains the multifaceted, expansive drug-binding pocket, which is composed of several separate, but linked, binding sites.
