Tool: How Study Aromatic-Aromatic Interactions And Amino-Aromatic Interactions Of Protein-Ligands Complexes In The Pdb.

Dear all,

What are the best ways to study aromatic-aromatic interactions and amino-aromatic interactions between protein binding site residues and ligands in the PDB. What are the best free and paid software I can use to do an excellent job.

Thank you,
Dr. Abubakar Abdullahi.

You could use iCn3D to get all interactions including aromatics (pi-stacking and pi-cation) in the menu "Analysis > Interactions". One example is at https://structure.ncbi.nlm.nih.gov/icn3d/share.html?CuXYgGLCukDeUKnJ6 enter image description here

Software and databases from CCDC can perfectly do this job, but it's paid. Also interaction fingerprints (IFP) can encode the aromatic interactions between protein and ligand: PLIF - opensource IFP library, honestly don't know if the aromatic interaction is included in it. FingerPrintLib - by Didier Rognan Lab, - can definitely do fingerprint calculation with detection of aromatic interaction (two types).

PS: Actually there are tons of literature about aromatic interaction of the amino acids and ligands in protein-ligand complexes.
