Metabolism‐dependent taxis towards (methyl)phenols is coupled through the most abundant of three polar localized Aer‐like proteins of Pseudomonas putida

摘要: Comparatively little is known about directed motility of environmental bacteria to common aromatic pollutants. Here, by expressing different parts a (methyl)phenol-degradative pathway and the use specific mutants, we show that taxis Pseudomonas putida towards (methyl)phenols dictated its ability catabolize compound. Thus, in contrast previously described chemoreceptor-mediated chemotaxis mechanisms benzoate, naphthalene toluene, response mediated metabolism-dependent behaviour. Here P. differentially expresses three Aer-like receptors are all polar-localized through interactions with CheA, inactivation most abundant Aer2 protein significantly decreases phenolics. In addition, participation sensory signal transduction composed PAS, GGDEF an EAL domain these compounds demonstrated. The results discussed context versatility coupling necessity for integrate diverse metabolic signals from native heterogeneous soil water environments.
