Figure 4. Comparison of the prim-pol domain with Pfu archaeal primase^3. Catalytic domains are in silver and structurally conserved regions are highlighted in green. Four equivalent residues (three acidic active-site residues and a neighboring histidine) are in orange. The archaeal primase contains an additional species-specific domain (blue).
