Interaction summary

HBA 4 HY 6 PI 3 CLASH 2

HBD/HBA · H-bonds (geometric)

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

Receptor context

1 kept / 0 excluded

Receptor context filtering: interactions and SASA are computed against protein atoms plus allowed cofactors/ions. Native ligand-like HETATM partners are excluded from scoring.
