DESCRIPTION

Also known as QACR_STAAM, qacR. Transcriptional repressor of qacA. Binds to IR1, an unusually long 28 bp operator, which is located downstream from the qacA promoter and overlaps its transcription start site. QacR is induced from its IR1 site by binding to one of many structurally dissimilar cationic lipophilic compounds, which are also substrates of QacA (By similarity). Homodimer. Binds cooperatively to DNA as a pair of dimers (By similarity).
