 The PDB file [[2yxj]] shows the structure of Bcl-Xl and ABT 737. ABT 737 is a potent inhibitor of Bcl-Xl (Kd = 1nM). It binds Bcl-xl in the same position as BAK does as can be seen in [[1bxl]].
 Interestingly the interface of Bcl-Xl is almost symmetric. There are <scene name='43/437742/2yxj_arg/6'>two positively charged residues</scene> Arg 100 and Arg 139.
