WebSep 16, 2024 · Pilin refers to a class of fibrous proteins that are found in 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 pili or fimbriae, bacterial pathogens often use their fimbriae to attach to host cells. WebF-pili are thin, flexible filaments elaborated by F (+) cells of Escherichia coli. They belong to the class of Gram-negative pili that function in horizontal gene transfer. F-pili are initially required to establish contacts between DNA donor and recipient cells.
