CC   -!- FUNCTION: Plays a role in processing non linear or branched viral DNA
CC       intermediates in order to promote the production of mature packaged
CC       unit-length linear progeny viral DNA molecules. Exhibits endonuclease
CC       and exonuclease activities and accepts both double-stranded and single-
CC       stranded DNA as substrate. Exonuclease digestion of DNA is in the 5'->
CC       3' direction and the products are 5'-monophosphate nucleosides.
CC       Additionally, forms a recombinase with the major DNA-binding protein,
CC       which displays strand exchange activity. {ECO:0000255|HAMAP-
CC       Rule:MF_04009}.
CC   -!- SUBUNIT: Interacts with major DNA-binding protein; this interaction
CC       increases the nuclease processivity of the alkaline exonuclease.
CC       {ECO:0000255|HAMAP-Rule:MF_04009}.
CC   -!- SUBCELLULAR LOCATION: Host nucleus {ECO:0000255|HAMAP-Rule:MF_04009}.
CC       Host cytoplasm {ECO:0000255|HAMAP-Rule:MF_04009}.
CC   -!- SIMILARITY: Belongs to the herpesviridae alkaline nuclease family.
CC       {ECO:0000255|HAMAP-Rule:MF_04009}.
