Chemotaxis is the cell’s system for directed movement which allows the cell to move towards nutrition sources as well as away from toxic substances. The chemotactic system is a complex chain of phosphorylation reactions. At the end of the chain is the flagellum-binding protein CheY. The phosphorylated CheY (CheY-p) binds the flagella and causes the cell to tumble in place, essentially remaining immotile. The phosphatase CheZ dephosphorylates CheY, causing CheY to unbind to the flagella, resulting in directed movement of the cell [1]. | Chemotaxis is the cell’s system for directed movement which allows the cell to move towards nutrition sources as well as away from toxic substances.

cheZ, chemotaxis regulator, protein phosphatase for CheY
Usage and Biology
Chemotaxis is the cell’s system for directed movement which allows the cell to move towards nutrition sources as well as away from toxic substances. The chemotactic system is a complex chain of phosphorylation reactions. At the end of the chain is the flagellum-binding protein CheY. The phosphorylated CheY (CheY-p) binds the flagella and causes the cell to tumble in place, essentially remaining immotile. The phosphatase CheZ dephosphorylates CheY, causing CheY to unbind to the flagella, resulting in directed movement of the cell [1].
