Secondary structure and topology of SOTI-III. (a) Secondary-structure elements of SOTI-III. The four loops (mainly [beta]-turns) are labelled L1-L4. Green arrows indicate the three [beta]-strands. The short helix [alpha]1 is colored purple. Disulfide bonds are drawn as black lines. The cysteine residues involved are labelled I-VI. The red U-shaped line symbolizes the [beta]-hairpin with a [gamma]-turn of the inhibitor loop L4. (b) Topology of SOTI-III. Residue numbers for boundaries of secondary-structure elements are shown. The coloring of secondary-structure elements is the same as in (a).  [article HTML]
