Figure 1

Structure-based sequence alignment of the C-terminal domain of MutY and MutT. Boxed residues were mutated to alanines. Lines above or underneath of the sequences represent the α-helixes (α1 and α2) or β-sheets (βA–βE). The loops connecting α-helixes or β-sheets are marked with I–IV. The region G37–G59 (marked by a dotted line) of MutT is the pyrophosphohydrolase module with essential residues marked with stars. Identical residues between the C-terminal domain of MutY and MutT are marked with short vertical lines.
