FIGURE 2. — A, overall three-dimensional structure of Ara h 8 at three positions showing the backbone folding pattern with secondary structural elements. Ara h 8, like Bet v 1, has three α-helices flanking the seven-stranded β-sheet. B, superposition of Ara h 8 (shown in brown) and Bet v 1 (shown in blue). The ligand, ANS, is shown in atom type colors and is bound to Bet v 1 (PDB code 4A80). The overall fold of the two allergens is very similar, with three α-helices and seven β-strands, a root mean square deviation value of 1.7Å, and a sequence identity of 48%.
