The ribbon representation of the Fel d 1 oligomer. a Chains 1 and 2 are shown in blue and red colors, respectively. Each chain contains four helixes (H) linked to each other by three disulfide bonds (C3–C73, C44–C48, and C7–C70). b The surface-accessible residues within the previously identified IgE epitope are shown on oligomer Fel d 1. Orange sphere reveals the calcium ion. The PDB structures of the Fel d 1 oligomer (PDB code: 2ejn) are indicated by PyMol software
