QS operates by regulating the synthesis of a QS signal, Acyl Homoserine Lactone (AHL), and its cognate receptor, which doubles as a transcription factor that affects other gene transcriptional activities. In this blog we attempt to scrutinize a specific QS signal receptor, QscR, by looking into its structural characteristics, and comparing QscR with other homologous receptors such as LasR, TraR, CviR and SdiA to analyse what they may have in common or how they differ. We have also included a list of techniques which are employed in the structural study of QscR under 'Methodology'. References have been cited throughout and included together with acknowledgement at the last page. On top of each page there is a brief statement which summarizes the content.
