Overlay of cIAP1-BIR3 and XIAP-BIR3. The Cα-atom traces of the proteins are shown. cIAP1-BIR3 is shown in magenta and XIAP-BIR3 in gray. The conformation of cIAP-BIR3 from the caspase-9 peptide complex (this work) is superimposed on the XIAP-BIR3 structure as seen in the protein–protein complex of XIAP-BIR3 and caspase-9 (Shiozaki et al., 2003 ![]() |
