Figure 1 Structure of the Bacillus fragment with duplex DNA bound at the polymerase active site. The Bacillus fragment molecular surface is coloured according to its proximity to the DNA, with all points less than 3.5 ? coloured magenta, between 3.5 and 5.0 ? yellow, and greater than 5 ? blue. Bound water molecules were not included in this calculation.
