New insights into F-pilus structure, dynamics, and function
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.
