Figure 2. A: A stereo diagram showing the overall APC35832 structure. B: Superimposition of APC35832 and the Toprim domain of T7 DNA primase (PDB entry 1NUI), showing conserved acidic residue positions. APC35832 is colored pink, 1NUI is blue and conserved acidic residues are highlighted in green and yellow. C: The solvent-accessible surface colored according to electrostatic potential (blue positive, red negative, calculated with DS ViewerPro 6.0 [Accelerys Software]). The acidic surface pocket is visible, with the MES molecule shown as sticks.
