2.7.7.7 DNA-directed DNA polymeraseIUBMB Comments
Catalyses DNA-template-directed extension of the 3'- end of a DNA strand by one nucleotide at a time. Cannot initiate a chain de novo. Requires a primer, which may be DNA or RNA. See also EC 2.7.7.49 RNA-directed DNA polymerase.

beta-polymerase can copy a synthetic ribohomopolymer such as (A)n*(dT)12 as well as the corresponding deoxyribohomopolymer (dA)n*(dT)12 or activated DNA, alpha-polymerase utilizes the deoxyribohomopolymer (dA)n*dT12-18 eight times better than (A)n*dT12

5 cellular DNA template-dependent DNA polymerases are encoded by distinct genes: polymerase alpha, i.e. pol I, polymerase beta, only in vertebrates, polymerase gamma, required for mitochondrial DNA replication but encoded in the nucleus, polymerase delta, enzymes in mammalian cell contain tightly associated 3'-5'-exonuclease activities, 2 forms: proliferating cell nuclear antigen-dependent and a proliferating cell nuclear antigen-independent, also called DNA polymerase delta II, now named DNA polymerase epsilon, polymerase epsilon, tightly associated 3'-5'-exonuclease activity, formerly named DNA polymerase delta II
