3.A.6.2.1
Flagellar protein export system.  Infrequent ATP hydrolysis by the FliI6FliJ ring is sufficient for gate activation, allowing processive translocation of export flagellar protein substrates for efficient flagellar assembly (Minamino et al. 2014). FliO has been identified as a flagellar basal body chaparone protein (Fabiani et al. 2017). The flagellar protein export apparatus switches its substrate specificity when hook length has reached approximately 55 nm, and the hydrophilic C-terminal domain of FlhB is involved in this switching process (Inoue et al. 2019). A positively chargef region of Salmonella FliI is required for ATPase formation and efficient flagellar protein export (Kinoshita et al. 2021).
