HBD/HBA · H-bonds (geometric)
HBD = ligand donates H · HBA = ligand accepts H · ~ = weak (≥110°). Mode: permissive. Residues: 3.
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.
