Abstract excerpt
The DNA polymerase III holoenzyme (HE) is the primary replicative polymerase of Escherichia coli. The epsilon (epsilon) subunit of HE provides the 3'-->5' exonucleolytic proofreading activity for this complex. Epsilon consists of two domains: an N-terminal domain containing the proofreading exonuclease activity (residues 1-186) and a C-terminal domain required for binding to the polymerase (alpha) subunit...
