The paper determines the structure of the portal vertex and neck complex in the hyperthermophilic phage Oshimavirus, revealing a pressure-sensitive mechanism for terminating DNA packaging and triggering tail attachment.

The paper identifies an antisense RNA, ArrA, that inhibits DnaA production in Bacillus subtilis and affects sporulation timing.

This study compares the clamp loader mechanism in bacteria and eukaryotes, revealing structural and functional differences in clamp opening and p/t-junction binding.
