2CMP - PubMed Abstract: 
DNA packaging in tailed bacteriophages and in evolutionarily related herpesviruses is controlled by a viral-encoded terminase. As in a number of other phages, in the Bacillus subtilis bacteriophages SF6 and SPP1 the terminase complex consists of two proteins: G1P and G2P. The crystal structure of the N-terminal DNA-binding domain of the bacteriophage SF6 small terminase subunit G1P is reported. Structural comparison with other DNA-binding proteins allows a general model for the interaction of G1P with the packaging-initiation site to be proposed.
