Flagellar motor switch protein flim
Webvolve dynamics of elements of the motor stator or switch com-plex. Recent experiments show that the motor is a dynamic structure, with Mot proteins (21) and FliM molecules coming on and off (22, 23). Changes in number of stator elements and FliM molecules can induce changes in motor bias (and hence changes in mean intervals) (23, 24).

WebSep 23, 2014 · Direction switching in the flagellar motor of Escherichia coli is under the control of a complex on the rotor formed from the proteins FliG, FliM, and FliN. FliG lies at the top of the switch complex (i.e., nearest the membrane) and is arranged with its C-terminal domain (FliG C ) resting on the middle domain (FliG M ) of the neighboring subunit. WebJun 18, 1998 · The flagellar switch extends from the base of the flagellar motor into the cytoplasm (Figure 1) [6], [7].The switch is composed of three proteins — FliG, FliM and FliN — which are involved in flagellar assembly, flagellar rotation and controlling the direction of rotation [8].The amino terminus of FliM is the CheY docking site [4], …
WebThe flagellar motor switch proteins of strain RA are comprised of FliM, FliG, and FliN, and many of the genes related to these proteins were upregulated. Other genes related to flagellar function were also upregulated in the experiment ( Table 4 , Figure 5 ).
WebMar 3, 2024 · IMPORTANCE The bacterial flagellar motor is an ultrasensitive motor. Its output, the probability of the motor turning clockwise, depends sensitively on the occupancy of the protein FliM (a component on the switch complex of the motor) by the input CheY-P molecules.
