Figure 2: The predicted 3D structure model and the main chain interface structure. (a) Predicted 3D structure model of the yellow catfish IL-8. (b) Superimposed prediction model and native cartoon structures of the yellow catfish IL-8 and the human CXCL13. Rainbow structure represents the yellow catfish IL-8, while the purple line is the alpha carbon backbone of the human CXCL13. (c) Predicted 3D structure model of the yellow catfish IL-10. (d) Superimposed prediction model and native cartoon structures of the yellow catfish IL-10 and the human IL-20. Rainbow structure represents the yellow catfish IL-10, while the purple line is the alpha carbon backbone of the human IL-20.
