More model informationA molecular machine with a rotary motor builds a long protein filament involved in bacterial motility and attachment.
Bacteria live in complex ecologies, filled with competitors, environmental dangers, and defensive hosts. They face these challenges in many ways: by gathering together into tough biofilm communities, by sharing genetic information encoding useful proteins, and by picking up and moving when things look better elsewhere. Pili play an important role in all of these responses. Pili are long, thin protein filaments that help bacteria adhere to their local environment. They come in many shapes and sizes, and are deployed from the cell surface by complex assembly machines.
