Mignot and colleagues present an evolutionary scenario to explain the emergence of the two distinct machines — the Agl–Glt and Agl–Nfs complexes — that are involved in motility and assembly of the spore coat inMyxococcus xanthus. They argue that elucidation of the composition and mechanism of action of these complexes will improve our understanding of the evolution of macromolecular complexes.
