Protein name
RecName: Full=Head completion nuclease;
EC 3.1.-.-;

Comments [?]

Function During phage morphogenesis, plays an essential role in the head-tail joining step. The associated nuclease activity is essential for morphogenesis, possibly by cleaving packaged DNA to enable the joining of heads to tails. Displays both exo- and endonuclease activity.
Similarity Belongs to the Caudovirales head completion nuclease family.
