[[DNA polymerase]] '''(Dpo)''' reads a [[DNA|DNA strand]] and catalyzes the synthesis of its complementary strand.  Dpo sliding clamp is made of the complex of Dpo and [[Proliferating Cell Nuclear Antigen]] (PCNA) which encircles it.  The BRCT domain in Dpo is the C-terminal domain of breast [[cancer]] susceptibility protein.  The Klenow fragment is a large Dpo fragment produced upon cleavage of Dpo by [[Subtilisin|subtilisin]].  In the ''E. coli'', the EcDpo III subunits β, γ, δ, δ' are named clamp loader.  This complex assembles the β subunit sliding clamp unto the DNA.  '''Rev1''' is a '''Dpo''' involved in replication over DNA lesions.  '''Terminal deoxynucleotidyl transferase (TdT)''' is a Dpo expressed in immature lymphoid cells.  TdT adds nucleotides to exons during antibody gene recombination.  For more details see<br />

The images at the left and at the right correspond to one representative Dpo, ''i.e.'' the crystal structure of DNA polymerase I from ''Thermus aquaticus'' ([[1taq]]).  For more details see<br />
