Cartoon representation of two SMC subunits in the budding yeast cohesin (PDB: 7OGT) (a), the budding yeast condensin (PDB: 6YVU) (b) and the bacteria MukBEF (PDB: 7NYY) (c). The elbow structures of these SMC complexes are marked with red boxes. A break at each of the four coiled-coil helix is seen (inset).
