The epsilon subunit of the Escherichia coli replicative DNA polymerase III is the proofreading 3'-5' exonuclease. Structures of its catalytic N-terminal domain (epsilon186) were determined at two pH values (5.8 and 8.5) at resolutions of 1.7-1.8 A, in complex with two Mn(II) ions and a nucleotide product of its reaction, thymidine 5'-monophosphate ...
