Abstract
- Chemotaxis is crucial for the survival of bacteria, and the signaling systems associated with it exhibit a high level of evolutionary conservation. The architecture of the chemosensory array and the signal transduction mechanisms have been extensively studied in Escherichia coli. More recent studies have revealed a vast diversity of the chemosensory system among bacteria. Unlike E. coli, some bacteria assemble more than one chemosensory array and respond to a broader spectrum of environmental and internal stimuli. These chemosensory arrays exhibit a great variability in terms of protein composition, cellular localization, and functional variability. Here, we present recent findings that emphasize the extent of diversity in chemosensory arrays and highlight the importance of studying chemosensory arrays in bacteria other than the common model organisms.<br /> (Copyright © 2019 Elsevier Ltd.
