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. | Defined by 3 residues: THR:C-23 [auth C-21]CYS:C-29 [auth C-27]HIS:C-46 [auth C-44] | |
