Binds to the long stretches of ssDNA of the viral DNA replication intermediates created during the protein-primed mechanism of replication of the viral genome and attaches the viral DNA to the membrane of the infected cells. Required for the redistribution of replicating viral DNA from the initial replication site to membrane-associated sites surrounding the nucleoid. Required for the second pull step of DNA ejection. Homodimer; homooligomer. Interacts with DNA; one dsDNA binding subunit is constituted by three p16.7 dimers. Belongs to the phi29likevirus gp16.7 family.
