Pilin refers to proteins that create pilus structures in bacteria. These structures can be used for the exchange of genetic material, or as a cell adhesion mechanism. Although not all bacteria have pi

…c-u pilus system. This protein domain, has an important function in forming pili. These are virulence factors crucial for cell adhesion to the host and biofilm formation with successful infection. This protein domain consists of the adjacent Saf-Nte and Saf-pilin chains of the pilus-forming complex. They are…

Five stages of biofilm development (1) Initial attachment, (2) Irreversible attachment, (3) Maturation I, (4) Maturation II, and (5) Dispersion. Each stage of development in the diagram is paired with a photomicrograph of a developing P. aeruginosa biofilm. All photomicrographs are shown to the same scale.
