-==Overview==
+==R-type straight flagellar filament made of full-length flagellin==
-The bacterial flagellar filament is a helical propeller for bacterial, locomotion. It is a helical assembly of a single protein, flagellin, and, its tubular structure is formed by 11 protofilaments in two distinct, conformations, L- and R-type, for supercoiling. The X-ray crystal, structure of a flagellin fragment lacking about 100 terminal residues, revealed the protofilament structure, but the full filament structure is, still essential for understanding the mechanism of supercoiling and, polymerization. Here we report a complete atomic model of the R-type, filament by electron cryomicroscopy. A density map obtained from image, data up to 4 A resolution shows the feature of alpha-helical backbone and, some large side chains. The atomic model built on the map reveals, intricate molecular packing and an alpha-helical coiled coil formed by the, terminal chains in the inner core of the filament, with its intersubunit, hydrophobic interactions having an important role in stabilizing the, filament.
