Hi Xiangjun,
My new target structure is 1F1T from RCSB. It is a malachite green aptamer with a ligand called N,N'-TETRAMETHYL-ROSAMINE (ROS).
If you go to the PDB website and search for this PDB, you can see there is a stacking interaction between ROS and one of the adenine base in the 2D Diagram & Interactions.
http://www.rcsb.org/pdb/explore/explore.do?structureId=1f1t
My question is whether DSSR can detect such ligand and RNA interaction?
Here, I also attach the PDB file and json file that I generated for your convenience.
Best,
Honglue

Hi Xiangjun,
Also, generally speaking, can DSSR detect protein/peptide and nucleic acid stacking interaction? For example, the stacking between aromatic ring of Phenylalanine and nucleic acid base?

No, in general. This feature is beyong DSSR’s design scope, at least for now. Why not using the result from reported from the RCSB PDB website? It is an ‘authoritative’ resource, isn't it?

You may find SNAP helpful. Again, do not forget the many other resources/tools in the field.
