Figure 3: BR187–385 forms a β-sheet dimer with a saddle-like structure.

Intermolecular β-sheets are formed between symmetry mates of BR187–385 in the P4122 (PDB: 3ZGH) crystal structure with a total interface surface area (ISA) of 600 Å2. The sheet is stabilized by eight hydrogen bonds between the backbones of the two A1 strands. The molecules forming intermolecular β-sheets are colored grey and wheat. The view of the right panel was rotated by ~90° compared to the left panel. Hydrogen bond interactions are represented as dashed red lines.
