![2D <t>interactions</t> <t>diagram</t> of ligands bound to GluN1 LBD. Hydrophobic residues are shown in green, polar residues are shown in cyan, positively charged residues are shown in purple, and negatively charged residues are shown in orange. Hydrogen bonds are shown as purple arrows, π-cation interactions are shown as red lines, and salt bridges are shown as red-blue lines. The tip of the tear-drop shape points towards the side chain of the residue; dots on a connection indicate a residue not making contact with the ligand.

Figure Legend Snippet: Averaged triplicate GluN1 LBD-ligand interactions of the 1 µs simulations. Note that figure scales are different to improve the visibility of the data. Hydrogen bonds are defined as an H-Acceptor distance less than 2.8 Å and a Donor-H-Acceptor angle greater than 120. Hydrophobic interactions include pi-pi stacking, pi-cation interactions, and van der Waals interactions within 3.6 Å of ligand. Ionic interactions are defined as charged interactions within 3.6 Å of the ligand. Water bridges are defined as H-Acceptor distances less than 2.7 Å. Hydrogen bonds are shown in green, hydrophobic interactions are shown in lilac, ionic interactions are shown in magenta, and water bridges are shown in blue. For residues with more than one type of interaction, the interaction fraction can exceed 1. ( A ) Glycine bound to wild-type GluN1 LBD, ( B ) D-serine bound to wild-type GluN1 LBD, ( C ) Glycine bound to S688Y GluN1 LBD, ( D ) D-serine bound to S688Y GluN1 LBD. Graphs were generated using the Simulation Interactions Diagram module of Maestro 2021.4 [ , ].
