WebStructure, Function and Assembly of Flagellar Axial Proteins WebJan 25, 2024 · The bacterial flagellum is made up of the flagellin protein. Each flagellum has three parts, hook, shaft, and the basal body. This has a helical structure and very sharp bending outside the outermost membrane. This is called the hook. The hook is made up of different types of proteins. A long shaft runs between the hook and the basal body.
