The restoration of pre-stimulus levels of the chemotactic response regulator, CheY-P, is important for allowing bacteria to respond to new environmental stimuli. The members of this family, CheC, CheX, CheA and FliY are CheY-P phosphatase [1,2]. CheC appears to be primarily involved in restoring normal CheY-P levels, whereas FliY seems to act on CheY-P constitutively. CheD enhances the activity of CheC 5-fold, which is normally relatively low [1,2]. In some cases, the region represented by this entry is present as multiple copies.	Domain

C	protein-glutamate methylesterase (CheD) M-CSA #729	CheD is a regulatory protein involved in the signal transduction pathways that control bacterial chemotaxis. CheD deamidates receptor glutamine residues contained within a conserved structural motif and also hydrolyses glutamyl-methyl-esters at specific positions on it's target proteins. CheC is a signal-terminating phosphatase which down regulates CheD activity by mimicking the substrate.
