This dock of d-limonene in OR2B11 shows Tyr256 displaced “down” (i.e. in the cytoplasmic direction) from its pre-dock position (transparent image, lowercase label) near a position of forming a hydrogen bond with Glu115. Tyr256 is in an analogous location to the known highly conserved Trp6.48 important to activation of non-OR GPCRs. Almost all ORs have […]
