pfam13690: CheX (This model is not part of the current CDD release)
Chemotaxis phosphatase CheX
CheX is very closely related to the CheC chemotaxis phosphatase, but it dimerizes in a different way, via a continuous beta sheet between the subunits. CheC and CheX both dephosphorylate CheY, although CheC requires binding of CheD to achieve the activity of CheX. The ability of bacteria to modulate their swimming behaviour in the presence of external chemicals (nutrients and repellents) is one of the most rudimentary behavioural responses known, but the the individual components are very sensitively tuned.
