Crystal structure of CtMre11CD and comparison with Nbs1-bound and unbound SpMre11CD structures (SpMre11CD and SpMre11CD–Nbs1, respectively). (a) Structures of the dimer of the catalytic domains of SpMre11CD, CtMre11CD and SpMre11CD in complex with the Nbs1 peptide (purple; SpMre11CD–Nbs1; PDB entries 4fcx, 4yke and 4fbw, respectively). The models are displayed in ribbon representation. Mre11 protomers are highlighted in light and deep blue. (b) Details of the Mre11 dimer interface and the eukaryotic insertion loops (lime and brown). The conformation of the CtMre11CD insertion loops is similar to the conformation of the loops in the SpMre11CD–Nbs1 structure. |
