The Aer protein and the serine chemoreceptor Tsr independently sense intracellular energy levels and transduce oxygen, redox, and energy signals for Escherichia coli behavior.
We identified a protein, Aer, as a signal transducer that senses intracellular energy levels rather than the external environment and that transduces signals for aerotaxis (taxis to oxygen) and other energy-dependent behavioral responses in Escherichia coli. Domains in Aer are similar to the signaling domain in chemotaxis receptors and the putative oxygen-sensing domain of some transcriptional ...
متن کاملSalmonella Uses Energy Taxis to Benefit from Intestinal Inflammation
Chemotaxis enhances the fitness of Salmonella enterica serotype Typhimurium (S. Typhimurium) during colitis. However, the chemotaxis receptors conferring this fitness advantage and their cognate signals generated during inflammation remain unknown. Here we identify respiratory electron acceptors that are generated in the intestinal lumen as by-products of the host inflammatory response as in vi...
متن کاملCharacterization of CetA and CetB, a bipartite energy taxis system in Campylobacter jejuni
The energy taxis receptor Aer, in Escherichia coli, senses changes in the redox state of the electron transport system via an flavin adenine dinucleotide cofactor bound to a PAS domain. The PAS domain (a sensory domain named after three proteins Per, ARNT and Sim, where it was first identified) is thought to interact directly with the Aer HAMP domain to transmit this signal to the highly conser...
متن کاملExpression of Pseudomonas aeruginosa aer-2, one of two aerotaxis transducer genes, is controlled by RpoS.
Pseudomonas aeruginosa possesses two aerotaxis transducers, Aer and Aer-2. A deletion-insertion mutation of alternative sigma factor RpoS eliminated Aer-2-mediated aerotaxis but not Aer-mediated aerotaxis. Transcriptional analysis revealed that cheY2, cheA2, cheW2, and aer-2 were expressed in an RpoS-dependent manner as a single transcript.
متن کاملChemotaxis proteins and transducers for aerotaxis in Pseudomonas aeruginosa.
It was previously shown that the chemotaxis gene cluster 1 (cheYZABW) was required for chemotaxis. In this study, the involvement of the same cluster in aerotaxis is described and two transducer genes for aerotaxis are identified. Aerotaxis assays of a number of deletion-insertion mutants of Pseudomonas aeruginosa PAO1 revealed that the chemotaxis gene cluster 1 and cheR are required for aerota...
