RC STRAIN=ATCC BAA-918 / JCM 12380 / KOD1 RC {ECO:0000313|Proteomes:UP000000536}; RX PubMed=15710748; DOI=10.1101/gr.3003105; RA Fukui T., Atomi H., Kanai T., Matsumi R., Fujiwara S., Imanaka T.; RT "Complete genome sequence of the hyperthermophilic archaeon Thermococcus RT kodakaraensis KOD1 and comparison with Pyrococcus genomes."; RL Genome Res. 15:352-363(2005). CC -!- FUNCTION: Possesses two activities: a DNA synthesis (polymerase) and an CC exonucleolytic activity that degrades single-stranded DNA in the 3' to CC 5' direction. Has a template-primer preference which is characteristic CC of a replicative DNA polymerase. {ECO:0000256|HAMAP-Rule:MF_00325}. CC -!- CATALYTIC ACTIVITY: CC Reaction=Exonucleolytic cleavage in the 3'- to 5'-direction to yield CC nucleoside 5'-phosphates.; EC=3.1.11.1; Evidence={ECO:0000256|HAMAP- CC 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-COMP:11130, CC Rhea:RHEA-COMP:11131, ChEBI:CHEBI:33019, ChEBI:CHEBI:61560, CC ChEBI:CHEBI:83828; EC=2.7.7.7; Evidence={ECO:0000256|HAMAP- CC 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}.
