>cd05779 DNA_polB_epsilon_exo The 3'-5' exonuclease domain of eukaryotic DNA polymerase epsilon. DNA polymerase epsilon is a family-B DNA polymerase with a catalytic subunit that contains a DEDDy-type DnaQ-like 3'-5' exonuclease domain. It is one of the three DNA-dependent type B DNA polymerases (alpha and delta are the other two) that have been identified as essential for nuclear DNA replication in eukaryotes. DNA polymerase epsilon plays a role in elongating the leading strand during DNA replication. It is also involved in DNA repair. The catalytic subunit contains both polymerase and 3'-5' exonuclease activities. The N-terminal exonuclease domain contains three sequence motifs termed ExoI, ExoII and ExoIII, with a specific YX(3)D pattern at ExoIII. These motifs are clustered around the active site and are involved in metal binding and catalysis. DNA polymerase epsilon also carries a unique large C-terminal domain with an unknown function. Phylogenetic analyses indicate that it is ort
