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] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedCrystal structures of a binary Mg2+-form Dpo4-DNA complex with 1,N2-etheno-dG in the template strand as well as of ternary Mg2+-form Dpo4-DNA-dCTP/dGTP complexes with 8-oxoG in the template strand have been determined. Comparison of their conformations and active-site geometries with those of the corresponding Ca2+-form complexes revealed that the DNA and polymerase undergo subtle changes as a result of the catalytically more active Mg2+ occupying both the A and B sites. Metal-ion dependence of the active-site conformation of the translesion DNA polymerase Dpo4 from Sulfolobus solfataricus.,Irimia A, Loukachevitch LV, Eoff RL, Guengerich FP, Egli M Acta Crystallogr Sect F Struct Biol Cryst Commun. 2010 Sep 1;66(Pt, 9):1013-8.
