(A) Membrane topology of Vibrio FliF. (B) Schematic diagram of N-terminally and C-terminally deleted Vibrio FliF. (C) Motility of N-terminal deletion FliF in a soft agar plate. The fliF deletion mutant (NMB196) producing wild-type FliF, ΔN30FliF, and ΔN50FliF from the pBAD plasmids (Vec) were inoculated on a soft agar plate at 30°C for 5 h. Motility of C-terminal deletion FliF in soft agar plate. The fliF deletion mutant (NMB196) producing wild-type FliF, ΔC83FliF, and ΔC110FliF were inoculated on a soft agar plate at 30°C for 4 h.
