The ribbon model of intertwined Phl p 7 dimers. Monomers A and B are shown in yellow and green colors. a The N-terminal EF-hand calcium-binding motif of monomer A and C-terminal EF-hand calcium-binding motif of monomer B form upper EF-hands, while the C-terminal EF-hand calcium-binding motif of monomer A and N-terminal EF-hand calcium-binding motif of monomer B comprise lower EF-hands. The C-terminal Z-helices of two monomers form an intertwined equatorial belt. b This figure represents the side chains of the calcium-binding residues in the N- and C-terminal EF-hand calcium-binding motifs. The calcium ion (green) is in the middle of the loop. The Protein Data Bank (PDB) structures of Phl p 7 (PDB code: 1K9U) are shown by PyMol software
