The Pseudomonas aeruginosa Membrane Histidine Kinase BqsS/CarS Directly Senses Environmental Ferrous Iron (Fe2+)

Alexander Paredes, Chioma Iheacho, Kelly N. Chacón, Aaron T. Smith

This study characterizes PaBqsS, an iron-sensing membrane histidine kinase, showing it directly binds Fe2+ and its ATPase activity is stimulated by Fe2+.
