Figure 2

The HP35 structure before and after the binding event to the C3N3 surface. The left picture illustrated the initial structure of HP35. The six pictures in the right panels indicated the final conformations of HP35 binding to the C3N3 nanosheet. Three key aromatic residues (Phe47, Phe51, and Phe58), identified as the hydrophobic core of this protein, maintained the native conformation without significant changes.
