cheC | CheY-P phosphatase CheC; Involved in restoring normal CheY-P levels following the addition of attractant by increasing the rate of CheY-P hydrolysis. Is only 6% as active as FliY, which indicates that CheC may function after addition of an attractant to cope with increased levels of CheY-P whereas FliY may function constitutively to remove CheY-P around the flagellar switch to maintain an optimal level of CheY-P. In addition, it was shown to prevent methylation of the methyl-accepting chemotaxis proteins (MCPs). Inhibits CheD. (209 aa) | ||||
fliY | Flagellar motor switching and energizing phosphatase; Component of the flagellar switch. Binds CheY-P and increases its hydrolysis rate in vitro. May function constitutively to remove CheY-P around the flagellar switch to maintain an optimal level of CheY-P whereas CheC may function after addition of an attractant to cope with increased levels of CheY-P; Belongs to the FliN/MopA/SpaO family.
