-	Chemotaxis is the process by which bacteria sense chemicals in their environment. This is done through the use of chemoreceptors to sense a chemical gradient that they can follow towards higher concentrations of food or away from higher concentrations of poisons or other unfavorable conditions. The Tar chemoreceptor is involved with the sensing of aspartate, a common amino acid, by binding aspartate in the extracellular portion of the protein and then propagates a signal down the receptor to activate a pathway to alter movement.	+	Chemotaxis is the process by which bacteria sense chemicals in their environment.
