Interaction summary

HBD 1 HBA 2 HY 7 PI 3 CLASH 1

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

Native ligand reference

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