CC -!- FUNCTION: Poorly processive, error-prone DNA polymerase involved in CC untargeted mutagenesis. Copies undamaged DNA at stalled replication CC forks, which arise in vivo from mismatched or misaligned primer ends. CC These misaligned primers can be extended by PolIV. Exhibits no 3'-5' CC exonuclease (proofreading) activity. May be involved in translesional CC synthesis, in conjunction with the beta clamp from PolIII. CC {ECO:0000255|HAMAP-Rule:MF_01113}. CC -!- CATALYTIC ACTIVITY: CC Reaction=a 2'-deoxyribonucleoside 5'-triphosphate + DNA(n) = CC diphosphate + DNA(n+1); Xref=Rhea:RHEA:22508, Rhea:RHEA-COMP:17339, CC Rhea:RHEA-COMP:17340, ChEBI:CHEBI:33019, ChEBI:CHEBI:61560, CC ChEBI:CHEBI:173112; EC=2.7.7.7; Evidence={ECO:0000255|HAMAP- CC Rule:MF_01113}; CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; CC Evidence={ECO:0000255|HAMAP-Rule:MF_01113}; CC Note=Binds 2 magnesium ions per subunit. {ECO:0000255|HAMAP- CC Rule:MF_01113}; CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_01113}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01113}. CC -!- SIMILARITY: Belongs to the DNA polymerase type-Y family. CC {ECO:0000255|HAMAP-Rule:MF_01113}.
