Figure 2.
Interaction between symmetry-related mutant RAD521–212 rings. (a) Symmetry-related RAD52 rings are shown in blue, green and magenta. The boxed region of the mutant RAD521–212 ring structure is engaged in the crystal packing. The C-terminal region beyond the partially unfolded α-helix from one of the monomers, which interacts with the neighbouring RAD52 ring, is encircled by a dashed red oval. (b) A close-up view of the boxed region in (a). Ala102, Ala133 and Ala202 are located close to each other at the crystal-packing interface.
