'''Chemotaxis proteins''' direct cell movement according to certain chemicals in their environment.<ref>PMID:4598187</ref>
*'''CheY''' is a response regulator determining the swimming behaviour of the cell<ref>PMID:7623663</ref>.
*'''CheR''' is a SAM-dependent methyltransferase which binds to the C-terminus of some chemotaxis receptors and methylates neighbouring receptor molecules<ref>PMID:9628482</ref>.  See [[Molecular Playground/CheR]] and [[Chemotaxis receptor methyltransferase]].
*'''CheA''' is a histidine kinase which donates phosphoric groups to CheB and CheY to control swimming behaviour<ref>PMID:15090507</ref>.  See [[Molecular Playground/CheA]].
*'''CheB''' is a methyltransferase catalysing the demethylationof chemotaxis membrane receptors in ''Salmonella typhimurium''<ref>PMID:2991277</ref>.
*'''CheW''' participates in the control of CheA activity<ref>PMID:1992467</ref>. See [[Molecular Playground/Bacterial Chemotaxis Receptors]]
