Some of the building blocks used to assemble the central portion of the condensin anti-parallel coiled-coils. Five of the 10 coiled-coil fragments modelled in this study are shown in two views each, providing full annotation detail of intra- and interdomain cross-links (red brackets with Xwalk SAS distances if both lysines are on the same fragment). Intermolecular cross-links are specified in the inner panel images from residues numbered in red font. These fragments span the central portion of the coiled-coil and include two sites with multiple intermolecular links (see also figure 8c). Their location in the three-dimensional model is shown schematically in the overview schematic (SMC2 residue ranges 395?469 ?746?786 (top), 293?386 ?792?895 (bottom); SMC4 residue ranges 479 ??544 ?793?845 (top), 431?477 ?855?945 (middle), 342?421 ?949?1034 (bottom).
