Supplementary Figure S2: A, Schematic representation of the structure of HBS-101, B, Structural representation of MDK highlighting its N-terminal (cyan) and C-terminal (green) regions. The missing residues between these domains are marked, indicating the gap that required reconstruction. C, The patched structure of MDK after incorporating the missing residues through loop modeling. This step ensured the structural connectivity between the N- and C-terminal regions, maintaining the protein’s overall continuity. D, The final refined 3D structure of MDK following loop refinement and extensive molecular dynamics (MD) simulations.
