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:0000256|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:0000256|HAMAP-
CC Rule:MF_01113};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01113};
CC Note=Binds 2 magnesium ions per subunit. {ECO:0000256|HAMAP-
CC Rule:MF_01113};
CC -!- SUBUNIT: Monomer. {ECO:0000256|HAMAP-Rule:MF_01113}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01113}.
CC -!- SIMILARITY: Belongs to the DNA polymerase type-Y family.
CC {ECO:0000256|ARBA:ARBA00010945, ECO:0000256|HAMAP-Rule:MF_01113}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
