FIG 6.

A schematic model of flagellar assembly. The first panel shows an early stage of flagellar assembly with the MS-ring in the inner membrane. The second panel shows a FOMC assembled around the rod. The third panel shows an intermediate transitioning from rod to hook assembly. The fourth panel shows a subcomplex lacking the rod and hook. The last panel shows an FOMC. The final two structures are likely products of flagellar disassembly. EXP, export apparatus; OM, outer membrane; IM, inner membrane; PG, peptidoglycan layer.
