Project context and summary:

Leptospires encompass free-living and pathogenic environmental species that are exposed to endogenous and exogenous reactive oxygen species (ROS). The adaptation to oxidative stress has been thoroughly characterized in pathogenic Leptospira species but mechanisms involved in this adaptive response are unknown in saprophytic Leptospira, given that they possess different repertoire of oxidative stress-related factors. We have identified 3 transcriptional regulators (PerRA, PerRC, OxyR) that control anti-ROS enzymes (peroxidases and SOD) in L. biflexa. Our aim is to determine the genome-wide regulon of PerRA, PerRC and OxyR.
