CC   -!- FUNCTION: Probable terminase small subunit. The terminase lies at a
CC       unique vertex of the procapsid and is composed of two subunits, a small
CC       terminase subunit and a large terminase subunit. Both terminase
CC       subunits heterooligomerize and are docked on the portal protein to form
CC       the packaging machine. Once the capsid is packaged with the DNA, the
CC       terminase complex is substituted by the connector proteins gp15.
CC       {ECO:0000305|PubMed:24027307}.
CC   -!- SIMILARITY: Belongs to the skunalikevirus terminase small subunit
CC       family. {ECO:0000305}.
