Figure 2. Spatial resemblance of Lys17 in the BH4 domain of Bcl-2 and Lys87 in the BH3 domain of Bcl-XL.
Image showing the 3D-structures for Bcl-2 (left), Bcl-XL (middle) and their in silico superposition (right). Lys17 in the BH4 domain of Bcl-2 and Lys87 in the BH3 domain of Bcl-XL are indicated with arrows. The a.a. in green represent Lys17 and His94 in the BH4 and BH3 domain of Bcl-2 respectively. The a.a. in orange represent Asp14 and Lys87 in the BH4 and BH3 domains of Bcl-XL respectively. The images were obtained by using PyMOL.
