Figure 1

Schematic view of the structure of 8-aa-ring cystine-knot proteins. The six cysteines belonging to the cystine-knot are shown in yellow in this scheme and in the tables in additional files 1, 2 and 3. The remaining 4 amino-acids belonging to the 8-aa-ring are shown in green here as well as in the tables. G stands for the glycine residue that is conserved in all 8-aa-rings of cys-knot proteins. The black and yellow segments represent the three disulfide bridges forming the cystine-knot. The size of the ring is exagerated compared to that of the loops for the sake of clarity.
