Circles I and II indicate altered atoms between these two ligands. This result implies that this loss of the statistically preferred interactions with His84 main chain causes 10-fold gain of IC50 value in 2r3k complex from 2r3j, and the position II should be a carbon atom rather than a nitrogen atom for higher affinity.

G., Bhandary, and Krishna. See our ligand previous interaction paper for details about the statistics and the methods. Users can investigate how statistically overrepresented each atomic contacts in the PDB, and what proteinligand complex uses similar interactions, for any kind of atomic contacts rather than well-known predefined types of interactions. In the position I, that was an aromatic nitrogen atom and aromatic carbon atom in 2r3j and 2r3k, respectively, interacted with Leu134 residue by a CH interaction. Amino acid residues recognizing the specified atom will then appear, and interactions will be depicted as lines between atoms (Figure 2 B). The structures of these two ligands were shown in Figure 3 A PDB: 2r3j and B PDB: 2r3k (they were not in the pre-calculated dataset thus users need upload the PDB files).

Users can view interactions in the Jmol viewer by clicking check boxes in the tables. When the Mahalanobis distance between an interaction pattern and a position of atomic contacts, was.5, the interaction pattern was annotated onto the contacting pair.

What makes this significant difference in binding affinity is unclear, because these atoms did not make hydrogen bonds with the binding sites and there was no significant structural change in amino acid residues in binding sites.Figure 1 Methods for defining interaction patterns.In the annotations of interacting pairs, assignment to an interaction pattern of each contact and statistical preferences of the patterns are presented.
