Interestingly, overexpression of the P1 domain largely rescues the defect caused by removal of P2, further indicating that productive interactions between CheY and phosphorylated P1 do not require P2, and that P2 likely functions to increase the CheY ...
WebAn attractant decreases the rate of autophosphorylation of CheA, and a repellent increases the rate of autophosphorylation. Thus attractants promote CCW (counterclockwise) rotation and smooth swimming, whereas repellents promote CW (clockwise) rotation and tumbling.
