Figure 2. The crystal structure of GLIC bound with five ketamine molecules.
(a) A side view of the structure with ketamine molecules in purple color. A pair of principal and complementary subunits for ketamine binding is depicted in yellow and cyan, respectively. Note that ketamine is a few Å below loop C. (b) A stereo view of the 2Fo-Fc electron density map, contoured at 1.0 σ level, for the ketamine binding site. See also Figures S1 and S2.
