'''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'''
===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===




==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.
The line below this paragraph, {{ABSTRACT_PUBMED_12417307}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 12417307 is the PubMed ID number.
