Fig. 6

a The superimposition of the modeled ternary complexes of VCB/753b/BCL-xL and VCB/753b/BCL-2. The Cα RMSD of BCL-xL and BCL-2 is 6.7 Å. b The computational model of catalytic transition state of CRLVHL/753b/BCL-xL/UbcH5B-Ub/RBX1 with UbcH5B contacting with K87 of BCL-xL. The K87 of BCL-xL, C85, and D117 of UbcH5B are colored in blue, orange, and red, respectively. c The computational model of catalytic transition state of CRLVHL/753b/BCL-xL/UbcH5B-Ub/RBX1 with UbcH5B contacting with K20 of BCL-xL. d The computational model of catalytic transition state of CRLVHL/753b/BCL-2/UbcH5B-Ub/RBX1 with UbcH5B contacting with K17 of BCL-2.
