== Function ==
[https://www.uniprot.org/uniprot/DPO1_ECOLI DPO1_ECOLI] In addition to polymerase activity, this DNA polymerase exhibits 3' to 5' and 5' to 3' exonuclease activity. It is able to utilize nicked circular duplex DNA as a template and can unwind the parental DNA strand from its template.
