terminase small subunit [Pseudomonas tolaasii]
terminase small subunit( domain architecture ID 4118)
terminase small subunit binds to the packaging signal on phage DNA, allowing the terminase large subunit to cleave the DNA and thread it through the portal protein channel into the procapsid, powered by ATP hydrolysis

Terminase small subunit; Packaging of double-stranded viral DNA concatemers requires interaction of the prohead with virus DNA. This process is mediated by a phage-encoded DNA recognition and terminase protein. The terminase enzymes described so far, which are hetero-oligomers composed of a small and a large subunit, do not have a significant level of sequence homology. The small terminase subunit is thought to form a nucleoprotein structure that helps to position the terminase large subunit at the packaging initiation site. The actual alignment was detected with superfamily member COG3728: Pssm-ID: 470229 Cd Length: 131 Bit Score: 39.17 E-value: 1.72e-04
