Systems level analyses establish CodY as a multifaceted metabolic regulator integrating metabolism, motility and virulence in Listeria monocytogenes [ChIP-Seq]

To gain knowledge on L. monocytogenes differential CodY activity, we set on analyzing CodY's regulon in L. monocytogenes in both rich and minimal growth conditions using genome wide sequencing techniques. Remarkably, we identified for the first time a global regulatory role for CodY when BCAAs are limited, that are similar to those within the mammalian niche. Furthermore, our data establish CodY as a central regulator that integrates metabolism, motility, stress responses and virulence in L. monocytogenes. Overall design: Examination of CodY regulon in rich and minimal conditions.
