Protein

DNA polymerase catalytic subunit

Gene

UL54

Organism
Human cytomegalovirus (strain AD169) (HHV-5) (Human herpesvirus 5)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Replicates viral genomic DNA in the late phase of lytic infection, producing long concatemeric DNA. The replication complex is composed of six viral proteins: the DNA polymerase, processivity factor, primase, primase-associated factor, helicase, and ssDNA-binding protein (By similarity).By similarity

Catalytic activityi

Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).

Interactioni

Subunit structurei

Forms a complex with the ssDNA-binding protein UL57, the DNA polymerase processivity factor UL44, and the alkaline exonuclease UL98. Interacts with the putative helicase-primase complex composed of UL70, UL102 and UL105 proteins; these interactions may coordinate leading and lagging strand DNA synthesis at the replication fork (By similarity).By similarity
