3D structure model of BoTRAP1 constructed by using SWISS-MODEL. a Crystal structure of PvTRAP (residues 25-283). The structure of PvTRAP is shown as a cartoon (left) and surface structure (right). The Mg²⁺ ion at the ligand binding site was colored in yellow. The α-helices were shown as red, and yellow indicates β-strands. b Predicted BoTRAP1 structure (residues 44-297). The 3D structure in identical orientations contains six α-helices (α1 and α6) and seven β-strands (β1 to β7). The BoTRAP1 vWFA domain also includes a metalion-dependent adhesion site (MIDAS) for binding ligand. The figure on the left shows the cartoon structure of BoTRAP1, and the figure on the right shows BoTRAP1 surface structure
