CC -!- FUNCTION: The terminase small subunit binds to the packaging initiation
CC site and regulates the ATPase activity of the terminase large subunit.
CC The terminase lies at a unique vertex of the procapsid and is composed
CC of two subunits, a small terminase subunit involved in viral DNA
CC recognition (packaging sequence), and a large terminase subunit
CC possessing endonucleolytic and ATPase activities. Both terminase
CC subunits heterooligomerize and are docked on the portal protein to form
CC the packaging machine. The terminase large subunit exhibits
CC endonuclease activity and cleaves the viral genome concatemer at the
CC long non-permuted direct terminal repeats. Once the capsid is packaged
CC with the DNA, the terminase complex is substituted by neck proteins.
CC {ECO:0000250|UniProtKB:P17311}.
CC -!- SUBUNIT: Interacts with the terminase large subunit; the active complex
CC is probably heterooligomeric. {ECO:0000250|UniProtKB:P17311}.
CC -!- INDUCTION: Expressed in the late phase of the viral replicative cycle.
CC {ECO:0000305|PubMed:15661140}.
