Figure 7

(A) A schematic model for pilus assembly.

(B) Proposed atomic model of a FimA pilus filament. FimA subunits are colored alternately in red and cyan.

(C-D) Topological diagram of one assembled subunit in a type V pilus assembly (C) compared to that of type I pilus (D). Donor strands are colored red.
