== Function ==
[https://www.uniprot.org/uniprot/TERS_BPG20 TERS_BPG20] The terminase small subunit binds to the packaging initiation site and regulates the ATPase activity of the terminase large subunit (By similarity). The terminase lies at a unique vertex of the procapsid and is composed of two subunits, a small terminase subunit involved in viral DNA recognition (packaging sequence), and a large terminase subunit (By similarity). Both terminase subunits heterooligomerize and are docked on the portal protein to form the packaging machine (By similarity).[UniProtKB:P04893]
