    A peptide corresponding to the BH3 region of the proapoptotic protein, BID, could be bound in the cleft of the antiapoptotic protein, BCL-w. This binding induced major conformational rearrangements in both the peptide and protein components of the complex and led to the displacement and unfolding of the BCL-w C-terminal alpha-helix. The structure of BCL-w with a bound BID-BH3 peptide was determined using NMR spectroscopy and molecular docking. These studies confirmed that a region of 16 residues of the BID-BH3 peptide is responsible for its strong binding to BCL-w and BCL-x(L). The interactions of BCL-w and the BID-BH3 peptide complex with dodecylphosphocholine micelles were characterized and showed that the conformational change of BCL-w upon lipid binding occurred at the same time as the release and unfolding of the BH3 peptide.
