Bacterial chemosensory systems are grouped into 17 flagellar classes (F1-17). Here the authors employ electron cryotomography and comparative genomics to characterise the chemosensory arrays in γ-proteobacteria and identify a structural distinct for

The marine pathogen Vibrio vulnificus senses and responds to environmental stimuli via two chemosensory systems and 42-53 chemoreceptors. Here, we present an analysis of the V. vulnificus Aer2 chemoreceptor, VvAer2, which is the first V. vulnificus c

The Aer2 receptor from Pseudomonas aeruginosa has an O2-binding PAS-heme domain that stabilizes O2 via a Trp residue in the distal heme pocket. Trp rotates ∼90° to bond with the ligand and initiate signaling. Although the isolated PAS domain is mo

PAS domains are widespread, versatile domains found in proteins from all kingdoms of life. The PAS fold is composed of an antiparallel β-sheet with several flanking α-helices, and contains a conserved cleft for cofactor or ligand binding. The last

The Aer2 chemoreceptor from Pseudomonas aeruginosa is an Osub2/subsensor involved in stress responses, virulence, and tuning the behavior of the chemotaxis (Che) system. Aer2 is the sole receptor of the Che2 system. It is soluble, but membrane associ

In this study, we provide the first characterization of a chemoreceptor from Leptospira interrogans, the cause of leptospirosis. This receptor is related to the Aer2 receptors that have been studied in other bacteria. In those organisms, Aer2 is a so

HAMP domains are signal relay modules in >26,000 receptors of bacteria, eukaryotes, and archaea that mediate processes involved in chemotaxis, pathogenesis, and biofilm formation. We identify two HAMP conformations distinguished by a four- to two-hel

Pseudomonas aeruginosa is an opportunistic pathogen that senses and responds to its environment via four chemosensory systems. Oxygen activates the Che2 chemosensory system by binding to the PAS-heme domain of the Aer2 receptor. Ostensibly, the outpu

How complex, multi-component macromolecular machines evolved remains poorly understood. Here we reveal the evolutionary origins of the chemosensory machinery that controls flagellar motility in Escherichia coli. We first identify ancestral forms stil
