Figure 4. The binding profiles of SBFI-26 in the canonical sites of FABP5 and FABP7.
(A) The FABP5-SBFI-26 canonical position (cyan). The carboxyl group of SBFI-26 forms a salt bridge with Arg129 and hydrogen bonds with Tyr131 and Arg109. Water molecules are shown as red spheres. (B) In the FABP7-SBFI-26- complex, the carboxyl group of SBFI-26 forms a salt bridge with Arg127 and hydrogen bonds with Tyr129, Arg107, and Thr54. SBFI-26 specific interactions between the carbonyl group and Gly34 and Thr37 are mediated by a water molecule. (C) Hydrophobic interactions between SBFI-26 and FABP7.
