This entry represents the N-terminal domain of terminase large subunits found in a variety of the Caudovirales and prophage regions of bacterial genomes. It includes the terminase large subunit of Bacteriophage T4 (terminase gene 17, Gp17) [1,3]. Homologues are also found in Gene Transfer Agents (GTA) [2], including ORFg2 (RCAP_rcc01683) of the GTA of Rhodobacter capsulatus (Rhodopseudomonas capsulata) [see Fig.1, in 4].	Domain
