  Large protein complexes are assembled from protein subunits to form a
specific structure. In our theoretic work, we propose that assembly into the
correct structure could be reliably achieved through an assembly line with a
specific sequence of assembly steps. Using droplet interfaces to position
compartment boundaries, we show that an assembly line can be self organized by
active droplets. As a consequence, assembly steps can be arranged spatially so
that a specific order of assembly is achieved and incorrect assembly is
strongly suppressed.
