== The BphP / PpsR system ==
 
-
PpsR1 is a redox sensitive activator. It binds DNA under anaerobic conditions, and forms a tetramer via a disulfide bond. This interaction is ablated in the mutant PpsR1-C429S; meaning that we should be able to mimic an anaerobic system even under aerobic conditions.
 
-
 
-
PpsR2 is a transcriptional repressor, regulated by BphP.
 
-
 
-
PpsR1 and PpsR2 bind to TGTN_12ACA possibly arranged in tandem witha 7 base spacer. The affinity for both PpsRs are around 100nM.
 
-
 
-
BphP (or BrBphP for the Brayrhizobium variant) is sensitive to far-red light (~770nm) and controls PpsR1.
