1 Conformational reorganization of the amino-terminal four-helix bundle (22-kDa fragment) of apolipoprotein E (apoE) in binding to the phospholipid dimyristoylphosphatidylcholine (DMPC) to form discoidal particles was investigated by introducing single, double, and triple interhelical disulfide bonds to restrict the opening of the bundle. Dimyristoylphosphatidylcholine apolipoprotein E Homo sapiens
2 Conformational reorganization of the amino-terminal four-helix bundle (22-kDa fragment) of apolipoprotein E (apoE) in binding to the phospholipid dimyristoylphosphatidylcholine (DMPC) to form discoidal particles was investigated by introducing single, double, and triple interhelical disulfide bonds to restrict the opening of the bundle. Dimyristoylphosphatidylcholine apolipoprotein E Homo sapiens
3 Interaction of apoE with DMPC was assessed by vesicle disruption, turbidimetric clearing, and gel filtration assays. Dimyristoylphosphatidylcholine apolipoprotein E Homo sapiens
4 The results indicate that the formation of apoE.DMPC discoidal particles occurs in a series of steps. Dimyristoylphosphatidylcholine apolipoprotein E Homo sapiens
