4 protein-contact clashes 4 intramolecular clashes 72% of hydrophobic surface is solvent-exposed (13/18 atoms). Large non-polar area without protein contacts incurs a desolvation penalty and will reduce binding affinity. Consider truncating or replacing the exposed fragment.

Interaction summary

HBD 3 HBA 7 PC 1 HY 1 PI 0 CLASH 4

HBD/HBA · H-bonds (geometric)

HBD = ligand donates H · HBA = ligand accepts H · ~ = weak (≥110°). Mode: permissive. Residues: 7.

PC · Polar contacts (possible, no H geometry)

HBD?/HBA? — heavy-atom distance only, H geometry unavailable. May be real H-bonds.

PI · π–π interactions

No pi · π–π interactions detected for this pose.

HY · Hydrophobic contacts

CLASH · Clashes
