CC -!- FUNCTION: Possesses two activities: a DNA synthesis (polymerase) CC and an exonucleolytic activity that degrades single-stranded DNA CC in the 3' to 5' direction. Has a template-primer preference which CC is characteristic of a replicative DNA polymerase. CC {ECO:0000256|HAMAP-Rule:MF_00325}. CC -!- CATALYTIC ACTIVITY: CC Reaction=Exonucleolytic cleavage in the 3'- to 5'-direction to CC yield nucleoside 5'-phosphates.; EC=3.1.11.1; CC Evidence={ECO:0000256|HAMAP-Rule:MF_00325}; CC -!- CATALYTIC ACTIVITY: CC Reaction=a 2'-deoxyribonucleoside 5'-triphosphate + DNA(n) = CC diphosphate + DNA(n+1); Xref=Rhea:RHEA:22508, Rhea:RHEA- CC COMP:11130, Rhea:RHEA-COMP:11131, ChEBI:CHEBI:33019, CC ChEBI:CHEBI:61560, ChEBI:CHEBI:83828; EC=2.7.7.7; CC Evidence={ECO:0000256|HAMAP-Rule:MF_00325}; CC -!- SUBUNIT: Heterodimer of a large subunit and a small subunit. CC {ECO:0000256|HAMAP-Rule:MF_00325}. CC -!- SIMILARITY: Belongs to the DNA polymerase delta/II small subunit CC family. {ECO:0000256|HAMAP-Rule:MF_00325}.
