Sequestration of membrane-bound tocopherol by αTTP mutants.
A, location of AVED-affected residues relative to the ligand-binding
pocket of αTTP. Plotted after Meier et al.
((42) Protein Data Bank code
1OIP). B, time-dependent changes in FRET between NBD-tocopherol and
fluorescent liposomes in the presence of wild type (WT), R192H,
E141K, H101Q, or R59W variants of αTTP (30 μm active
protein). Conditions are as in Fig.
