Structure of QacR E90Q bound to Ethidium
Template:ABSTRACT PUBMED 21264225
Function
[QACR_STAAM] 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).
About this Structure
3pm1 is a 2 chain structure with sequence from Staphylococcus aureus. Full crystallographic information is available from OCA.
