Small conserved region in the C terminus regulates phospholipid transfer. A, phospholipid transfer activity of truncated forms of PFA0210c in vitro. Numbers indicate the C-terminal residue in the truncations. B, phospholipid transfer activity of point mutations in truncated proteins and full-length mutations. Indicated are the C terminus and in parentheses the point mutations (see Fig. 1B for location of mutated residues). C, phospholipid transfer activity of a double mutant and control proteins. All assays were performed in triplicate. Error bars indicate standard deviation.
