Figure 6

View of the hydrogen bonding pattern surrounding Asn-359. Asn-359 in UmuC (magenta) and Glu-1156 in the Pol III peptide (blue) are shown. The glutamate side chain in Pol III forms hydrogen bonds with a network of solvent molecules (all shown molecules relate to Pol III), which in turn interact with Arg-152 and, potentially, the side chain of His-175, resulting in a change in orientation of this residue. Asn-359 forms a hydrogen bond with Arg-152 in Pol V altering its position relative to the Pol III structure.
