PubMed Abstract: Members of the Pol II family of DNA polymerases are responsible for chromosomal replication in eukaryotes, and carry out highly processive DNA replication when attached to ring-shaped processivity clamps. The sequences of Pol II polymerases are distinct from those of members of the well-studied Pol I family of DNA polymerases. The DNA polymerase from the archaebacterium Desulfurococcus strain Tok (D. Tok Pol) is a member of the Pol II family that retains catalytic activity at elevated temperatures.
