Bacteria transduce signals across the membrane using two-component systems (TCSs), consisting of a membrane-spanning sensor histidine kinase and a cytoplasmic response regulator. In gram-negative bacteria, the PhoPQ TCS senses cations and antimicrobial peptides, yet little is known about the structural changes involved in transmembrane signaling. We construct a model of PhoQ signal transduction using Bayesian inference, based on disulfide crosslinking data and homologous crystal structures. The ...[more]
