Figure 6. Models of the BC2L-C hexamer with N-terminal domains in blue and C-terminal domains in green.

A. Best manual fit of the different domains of BC2L-C hexamer in the ab-initio SAXS envelop. B. Two possible arrangements of trimers that could correspond to the manual fit. C. Orthogonal orientations of the mode I. Linkers have been schematized by dotted lines. Calcium and carbohydrate ligands (fucose for the N-terminus and mannose for C-terminus) are represented by spheres.
