Interaction summary

HBD 2 HBA 1 PC 1 HY 3 PI 3 CLASH 0

HBD/HBA · H-bonds (geometric)

HBD = ligand donates H · HBA = ligand accepts H · ~ = weak (≥110°). Mode: permissive. Residues: 2.

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

Native π–π recall is disabled because no explicit native π–π reference was stored.

HY · Hydrophobic contacts

CLASH · Clashes

No clash · clashes detected for this pose.

Native ligand reference

★ reference
Interaction fingerprint calculated directly from the uploaded native ligand without docking. Current H-bond mode: permissive.
