Figure 3
Schematic representation of the de novo design workflow and the final AlphaFold2-predicted structure. (a) A flowchart outlines the sequential use of Rosetta BluePrintBDR, ProteinMPNN and AlphaFold2 to generate candidate sequences featuring a left-handed βαβ motif. (b) The top-scoring AlphaFold2 model is shown in two parts. In the upper ribbon diagram, the protein is color-coded by pLDDT (orange → yellow → light blue → dark blue) to indicate increasing local confidence; the average pLDDT value is 97.0 and the predicted TM-score (pTM) is 0.84, reflecting high overall confidence. Lighter, warmer hues mark lower-confidence regions that may deviate from the in silico model in the crystal structure. In the lower ribbon diagram, the left-handed βαβ motif is highlighted in orange, emphasizing its location and potential structural significance.
