Fig. 5From: The roles of aromatic residues in the glycine receptor transmembrane domainA Y228 and W286 are well positioned to form a T-type π–π interaction; B These residues, with Y406,W407 and Y410, form an aromatic cluster at the top of the M1/M3/M4 interface. C Y406 could form a hydrogen bond (green dashes) with either A282 or Y228; the data better support the formerBack to article page
