Function[DPO4_SULSO] Poorly processive, error-prone DNA polymerase involved in untargeted mutagenesis. Copies undamaged DNA at stalled replication forks, which arise in vivo from mismatched or misaligned primer ends. These misaligned primers can be extended by PolIV. Exhibits no 3'-5' exonuclease (proofreading) activity. It is involved in translesional synthesis.[HAMAP-Rule:MF_01113] Publication Abstract from PubMedDamaged goods: The unstable DNA adduct N(2) ,3-ethenoguanine, a product of both exposure to the carcinogen vinyl chloride and of oxidative stress, was built into an oligonucleotide, using an isostere strategy to stabilize the glycosidic bond. This modification was then used to examine the cause of mutations by DNA polymerases, in terms of both the biochemistry of the lesion and a structure of the lesion within a polymerase.
