Figure 1

Signaling pathway of chemotaxis. A kinase CheA phosphorylates itself and transfers the phosphate to CheB or CheY. The state of the chemoreceptor modification controls the efficiency of CheA phosphorylation and consequently the CheY phosphorylation level. Receptors take active or inactive form; active receptor complex undergo autophosphorylation of CheA. It can be methylated by CheR. Inactive receptor complex can be demethylated by phosphorylated form of CheB.
