'''X-ray structure of the GluR2 ligand-binding core (S1S2J) in complex with (S)-Des-Me-AMPA at 1.97 A resolution, Crystallization in the presence of zinc acetate'''<br />


==Overview==
==Overview==
X-ray structures of the GluR2 ligand-binding core in complex with, (S)-Des-Me-AMPA and in the presence and absence of zinc ions have been, determined. (S)-Des-Me-AMPA, which is devoid of a substituent in the, 5-position of the isoxazolol ring, only has limited interactions with the, partly hydrophobic pocket of the ligand-binding site, and adopts an, AMPA-like binding mode. The structures, in comparison with other agonist, complex structures, disclose the relative importance of the isoxazolol, ring and of the substituent in the 5-position for the mode of binding. A, relationship appears to exist between the extent of interaction of the, ligand with the hydrophobic pocket and the affinity of the ligand.
