Tailed bacteriophages and herpesviruses package DNA inside the viral capsid by a powerful molecular motor. This packaging machine is composed of the portal protein, which provides a gate for DNA entry, the large terminase subunit whose ATPase activity fuels DNA translocation, and most frequently, a small terminase subunit that recognizes the viral packaging site. Here we review the mechanisms how the virulent Bacillus subtilis phage SPP1 packages DNA into a preformed procapsid. Encapsidation of… CONTINUE READING
