Schematic view of the arrangements of the six anti-parallel beta-strands (β1–β6, yellow), the two short alpha helices (α1–α2, red). The arrangement of the five disulfide bonds (SS1–SS5) as marked in the amino-acid sequence are shown at the bottom. The loops a, b, and c are marked. Gln1838 is marked by blue arrow and Lys1801 by a red arrow.
