Cover Story: The archaellum is a rotary molecular propeller that enables archaea to swim, follow nutrients, evade perils and conquer new habitats. While functionally analogous to bacterial flagella, it is distinct in structure and mechanism. Unlike the bacterial flagellum, which is powered by a proton motive force, the archaellum is driven by ATP hydrolysis. It is composed of protein subunits called archaellins and assembled by a specialised molecular machinery homologous to bacterial type IV pilus systems. Studying its structure and dynamics offers fresh insight into the evolutionary divergence of motility systems and inspires innovation in nanotechnology and molecular engineering. View this paper
