Specialized DNA polymerases are required in both prokaryotic and eukaryotic cells for bypassing sites of template DNA damage that arrest high-fidelity DNA replication. Recent studies in the literature provide hints of the complexity of DNA switching between polymerases for translesion DNA synthesis (TLS) and those for normal DNA replication.

Polymerases:

Dpo4

Topics:

Health/Disease, Fidelity

Note:

The review compares processivity and termination of DNA synthesis opposite a CPD in template DNA by different polymerases including Dpo4 and describes role of “little finger” domain based on structural data for Dpo4.

Using Polbase tables:

Sorting:

Tables may be sorted by clicking on any of the column titles. A second click reverses the sort order. <Ctrl> + click on the column titles to sort by more than one column (e.g. family then name).

Filtering:

It is also possible to filter the table by typing into the search box above the table. This will instantly hide lines from the table that do not contain your search text.
