DNA polymerase type-B zeta subfamily catalytic domain. DNA polymerase (Pol) zeta is a member of the eukaryotic B-family of DNA polymerases and distantly related to DNA Pol delta. Pol zeta plays a major role in translesion replication and the production of either spontaneous or induced mutations. Apart from its role in translesion replication, Pol zeta also appears to be involved in somatic hypermutability in B lymphocytes, an important element for the production of high affinity antibodies in response to an antigen.

DNA polymerase type-B family catalytic domain. DNA-directed DNA polymerases elongate DNA by adding nucleotide triphosphate (dNTP) residues to the 5'-end of the growing chain of DNA. DNA-directed DNA polymerases are multifunctional with both synthetic (polymerase) and degradative modes (exonucleases) and play roles in the processes of DNA replication, repair, and recombination. DNA-dependent DNA polymerases can be classified in six main groups based upon their phylogenetic relationships with E. coli polymerase I (class A), E. coli polymerase II (class B), E. coli polymerase III (class C), euryarchaeota polymerase II (class D), human polymerase beta (class x), E. coli UmuC/DinB, and eukaryotic RAP 30/Xeroderma pigmentosum variant (class Y). Family B DNA polymerases include E. coli DNA polymerase II, some eubacterial phage DNA polymerases, nuclear replicative DNA polymerases (alpha, delta, epsilon, and zeta), and eukaryotic viral and plasmid-borne enzymes. DNA polymerase is made up of distinct domains and sub-domains. The polymerase domain of DNA polymerase type B (Pol domain) is responsible for the template-directed polymerization of dNTPs onto the growing primer strand of duplex DNA that is usually magnesium dependent. In general, the architecture of the Pol domain has been likened to a right hand with fingers, thumb, and palm sub-domains with a deep groove to accommodate the nucleic acid substrate. There are a few conserved motifs in the Pol domain of family B DNA polymerases. The conserved aspartic acid residues in the DTDS motifs of the palm sub-domain is crucial for binding to divalent metal ion and is suggested to be important for polymerase catalysis.

Three DNA-dependent DNA polymerases type B (alpha, delta, and epsilon) have been identified as essential for nuclear DNA replication in eukaryotes. Presently, no direct data is available regarding the strand specificity of DNA polymerase during DNA replication in vivo. However, mutation analysis supports the hypothesis that DNA polymerase delta is the enzyme responsible for both elongation and maturation of Okazaki fragments on the lagging strand.

Three DNA-dependent DNA polymerases type B (alpha, delta, and epsilon) have been identified as essential for nuclear DNA replication in eukaryotes. DNA polymerase (Pol) alpha is almost exclusively required for the initiation of DNA replication and the priming of Okazaki fragments during elongation. In most organisms no specific repair role, other than check point control, has been assigned to this enzyme. Pol alpha contains both polymerase and exonuclease domains, but lacks exonuclease activity suggesting that the exonuclease domain may be for structural purposes only.

DEDDy 3'-5' exonuclease domain of family-B DNA polymerases; The 3'-5' exonuclease domain of family-B DNA polymerases. This domain has a fundamental role in reducing polymerase errors and is involved in proofreading activity. Family-B DNA polymerases contain an N-terminal DEDDy DnaQ-like exonuclease domain in the same polypeptide chain as the polymerase domain, similar to family-A DNA polymerases. This 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 contain four conserved acidic residues that serve as ligands for the two metal ions required for catalysis. The exonuclease domain of family B polymerase also contains a beta hairpin structure that plays an important role in active site switching in the event of nucleotide misincorporation. Members include Escherichia coli DNA polymerase II, some eubacterial phage DNA polymerases, nuclear replicative DNA polymerases (alpha, delta, epsilon and zeta), and eukaryotic viral and plasmid-borne enzymes. Nuclear DNA polymerases alpha and zeta lack the four conserved acidic metal-binding residues. Family-B DNA polymerases are predominantly involved in DNA replication and DNA repair.
