Comments
[?]
| FUNCTION | Possesses two activities: a DNA synthesis (polymerase) and an exonucleolytic activity that degrades single-stranded DNA in the 3' to 5' direction. Has a template-primer preference which is characteristic of a replicative DNA polymerase. |
| CATALYTIC ACTIVITY | Reaction=a 2'-deoxyribonucleoside 5'-triphosphate + DNA(n) = diphosphate + DNA(n+1); Xref=Rhea:RHEA:22508, Rhea:RHEA-COMP:17339, Rhea:RHEA-COMP:17340, ChEBI:CHEBI:33019, ChEBI:CHEBI:61560, ChEBI:CHEBI:173112; EC=2.7.7.7; |
| CATALYTIC ACTIVITY | Reaction=Exonucleolytic cleavage in the 3'- to 5'-direction to yield nucleoside 5'-phosphates.; EC=3.1.11.1; |
| SUBUNIT | Heterodimer of a large subunit and a small subunit. |
| SIMILARITY | Belongs to the DNA polymerase delta/II small subunit family. |
