Prediction of 3D structure of KoOsmotin and comparison with its template CpOsmotin. The 3D models of KoOsmotin and its template (CpOsmotin, SMTL id: 4l2j.1) were produced by the homology modeling SWISS-MODEL. A. Pictures are predicted ribbon structures of KoOsmotin and its template, with α-helix (red) and β-strand (yellow), random coil (white). Three domains of KoOsmotin were indicated by red ellipses (domain I, amino acids1–68,102–142, 207–221. domain II, amino acids 143–206. domain III, amino acids 69–101). The three domains were similar in the 3D topology with other PR-5 proteins. B. View of the surface topology of KoOsmotin (left) and its template (right) showing the distribution of the electrostatic potentials. Protein surface was colored according to areas charged positively (blue), negatively (red) and neutrally (white). The acidic cleft was indicated by a black arrowhead. C. Figures are predicted trace structures of KoOsmotin and CpOsmotin and their superimposition
