Journal ArticleDOI
Identification of a Chemoreceptor for Tricarboxylic Acid Cycle Intermediates: DIFFERENTIAL CHEMOTACTIC RESPONSE TOWARDS RECEPTOR LIGANDS*
Jesús Lacal,Carlos Alfonso,Xianxian Liu,Rebecca E. Parales,Bertrand Morel,Francisco Conejero-Lara,Germán Rivas,Estrella Duque,Juan L. Ramos,Tino Krell +9 more
TL;DR: Equilibrium sedimentation studies show that malate, the chemoattractant that causes the strongest chemotactic response, stabilizes the dimeric state of McpS-LBD, the only chemoreceptor of TCA cycle intermediates in the strain under study.
Journal ArticleDOI
Pseudomonas putida F1 has multiple chemoreceptors with overlapping specificity for organic acids
Rebecca E. Parales,Rita A. Luu,Grischa Y. Chen,Xianxian Liu,Victoria Wu,Pamela Lin,Jonathan G. Hughes,Vasyl Nesteryuk,Juanito V. Parales,Jayna L. Ditty +9 more
TL;DR: At least three receptors work in concert to detect organic acids in P. putida F1, and expression of mcfS in the same mcpS deletion mutant demonstrated that, like McfR, McfS responds to succinate, malate, citrate and fumarate.
Journal ArticleDOI
Chemotaxis of Escherichia coli to Pyrimidines: a New Role for the Signal Transducer Tap
Xianxian Liu,Rebecca E. Parales +1 more
TL;DR: It is demonstrated that Escherichia coli RP437 is attracted to the pyrimidines thymine and uracil and the response was constitutively expressed under all tested growth conditions and indicated that the periplasmic domain of Tap is responsible for detecting p Skyrimidines and the Tsr signaling domain confers on Tapsr the ability to mediate efficient chemotaxis.
Journal ArticleDOI
Bacterial chemotaxis to atrazine and related s-triazines.

TL;DR: It is demonstrated that Pseudomonas sp.
Journal ArticleDOI
Chemotaxis to Pyrimidines and Identification of a Cytosine Chemoreceptor in Pseudomonas putida
TL;DR: A high-throughput quantitative capillary assay was developed and demonstrated that Pseudomonas putida strains F1 and PRS2000 were attracted to cytosine, but not thymine or uracil, and introduction of this gene into P. aeruginosa PAO1 conferred the ability to respond to cytOSine, the first report of a chemoreceptor for cytosines.
