Fig. 1: Structural models of DNA polymerase III in polymerization and editing mode.
From: Polymerization and editing modes of a high-fidelity DNA polymerase are linked by a well-defined path
The Pol III core (α, ε, and θ) bound to the DNA sliding clamp β in (a) polymerization mode and (b) editing mode. Pol III subunits are colored and labeled as follows: α in orange, ε in green, θ in magenta, and β in gray. The primer and template DNA strands are shown in light and dark gray respectively. The polymerase active site (in the α subunit) and exonuclease active site (in the ε subunit) are highlighted with circles.
