A ribbon diagram of the three-dimensional model of the predicted structure of the Sol g 4.1 protein constructed using S. invicta venom allergen Sol i 2 dimer (PDB accession no. 2ygu) as a template. The disulfide bonds are highlighted in tan. a Structural features of the Sol i 2 template dimerized by a disulfide bond on symmetrical residues Cys22. b The three-dimensional homology model of the predicted structure of the Sol g 4.1 protein revealed a structure stabilized by three disulfide bonds, and the molecular view is the same as the view shown for the right molecule in A. c The surface of Sol g 4.1 is marked according to amino acid residue properties: red – acidic residues; blue – basic residues; gray – apolar residues; green – polar residues; and yellow – aromatic residues. The molecule in the top view is the same as the molecule shown in B and has been rotated by 180° along the horizontal axis to show the bottom view. The model was obtained using Swiss-Model and was visualized with UCSF Chimera
