HBD/HBA · H-bonds (geometric)
HBD = ligand donates H · HBA = ligand accepts H · ~ = weak (≥110°). Mode: strict. Residues: 2.
PI · π–π interactions
Native π–π recall is disabled because no explicit native π–π reference was stored.
HY · Hydrophobic contacts
CLASH · Clashes
Native ligand reference
★ reference
Interaction fingerprint calculated directly from the uploaded native ligand without docking. Current H-bond mode: strict.
