Fig. 2. Ribbon diagram of Cdc14B. Two orthogonal views showing the overall structure of the Cdc14–phosphopeptide complex. The A- and B-domains are green and cyan, respectively, and the inter-domain α-helix is yellow. There is a large solvent-accessible surface area of 2108 Å² buried between the two domains. The phosphopeptide substrate is shown as a red coil, and key catalytic site loops are labelled. Figures were made with PyMOL (http://www.pymol.org).
