Function

function

Replicates viral genomic DNA. The replication complex is composed of six viral proteins: the DNA polymerase, processivity factor, primase, primase-associated factor, helicase, and ssDNA-binding protein. Additionally, the polymerase contains an intrinsic ribonuclease H (RNase H) activity that specifically degrades RNA/DNA heteroduplexes or duplex DNA substrates in the 5' to 3' direction. Therefore, it can catalyze the excision of the RNA primers that initiate the synthesis of Okazaki fragments at a replication fork during viral DNA replication.

Interaction

Subunit

Forms a complex with the ssDNA-binding protein UL29, the DNA polymerase processivity factor, and the alkaline exonuclease. Interacts with the putative helicase-primase complex subunit UL8; this interaction may coordinate leading and lagging strand DNA synthesis at the replication fork.
