<p style="text-align: justify;">Several chemosensory systems exist in bacteria. The one most studied is the chemotaxis of ''E. coli''. Polar clusters of membrane-spanning methyl accepting chemotaxis proteins (MCPs) are positioned in the ends of the rod shaped ''E. coli''.<br>

Transduction of the signal between the MCPs and the flagella motor is managed by a particular fine-tuned signalling cascade, which is governed by several intracellular proteins.<br></p>

<p style="text-align: justify;">Chemotaxis consists of three important phases: reaction, adaptation and relaxation. In the reaction phase, one of the MCPs sense the specific chemical gradient it responds to and the membrane protein activates the CheW enzyme.<br>
