Assembly of the small ribosomal subunit from an RNA strand and 33 proteins is an intricate and dynamic process. Two cryo-EM studies now provide insight into a complicated complex of at least 51 trans-factors that act on the preribosomal small subunit to sequentially fold it into a 3D molecular machine.
