X-ray crystal structure of PflLys49-PLA2 BPII. (a) Crystal structures of four molecules in an asymmetric unit. (b) Superimposition of the four molecules. (c) Disulfide bond network. The sulfur atoms are indicated as orange spheres. (d) Superimposition of molecules A and B on molecules C and D. (e) Superimposition of an alternative dimer (gray, PDB ID: 2Q2J) on molecule A of PflLys49-PLA2 BPII. (f) Superimposition of the conventional dimer (wheat PDB ID: 2Q2J) on molecule A of PflLys49-PLA2 BPII. (g) Surface charge distributions of the surface between molecules A and B. Surfaces comprising positive and negative charges are depicted as blue and red colors, respectively.
