Interestingly the interface of Bcl-Xl is almost symmetric. There are <scene name='43/437742/2yxj_arg/7'>two positively charged residues</scene> Arg 100 and Arg 139. | Interestingly the interface of Bcl-Xl is almost symmetric.

This symmetry can be exploited, a symmetric molecule can bind the same interface in two different ways thus increasing the "chance" of binding which means better binding affinity. | This symmetry can be exploited, a symmetric molecule can bind the same interface in two different ways thus increasing the "chance" of binding which means better binding affinity. | ||
