β-helical model of PbINP. A) Cartoon representation of the energy-minimized average structure of PbINP (residues 217-345) following a 5-ns MD simulation. β-strands are indicated by green arrows. The N and C termini are indicated. B) Cross-sectional view of PbINP. The β-standed SLTA and TQTA active sites are indicated, as is the β-stranded YGS multimerization interface. Oxygen atoms are coloured red, nitrogen atoms blue, and carbon atoms green.
