タイトル: Structure and genome ejection mechanism of phage P68.

要旨: Phages infecting can be used as therapeutics against antibiotic-resistant bacterial infections. However, there is limited information about the mechanism of genome delivery of phages that infect ...Phages infecting can be used as therapeutics against antibiotic-resistant bacterial infections. However, there is limited information about the mechanism of genome delivery of phages that infect Gram-positive bacteria. Here, we present the structures of native phage P68, genome ejection intermediate, and empty particle. The P68 head contains 72 subunits of inner core protein, 15 of which bind to and alter the structure of adjacent major capsid proteins and thus specify attachment sites for head fibers. Unlike in the previously studied phages, the head fibers of P68 enable its virion to position itself at the cell surface for genome delivery. The unique interaction of one end of P68 DNA with one of the 12 portal protein subunits is disrupted before the genome ejection. The inner core proteins are released together with the DNA and enable the translocation of phage genome across the bacterial membrane into the cytoplasm.

2019年1月31日: EMDBのIDの桁数の変更

EMDBのIDの桁数の変更

  • EMDBエントリに付与されているアクセスコード(EMDB-ID)は4桁の数字(例、EMD-1234)でしたが、間もなく枯渇します。これまでの4桁のID番号は4桁のまま変更されませんが、4桁の数字を使い切った後に発行されるIDは5桁以上の数字(例、EMD-12345)になります。5桁のIDは2019年の春頃から発行される見通しです。
  • EM Navigator/万見では、接頭語「EMD-」は省略されています。

2017年7月12日: PDB大規模アップデート

PDB大規模アップデート

  • 新バージョンのPDBx/mmCIF辞書形式に基づくデータがリリースされました。
  • 今回の更新はバージョン番号が4から5になる大規模なもので、全エントリデータの書き換えが行われる「Remediation」というアップデートに該当します。
  • このバージョンアップで、電子顕微鏡の実験手法に関する多くの項目の書式が改定されました(例：em_softwareなど)。
  • EM NavigatorとYorodumiでも、この改定に基づいた表示内容になります。

外部リンク:wwPDB Remediation / OneDepデータ基準に準拠した、より強化された内容のモデル構造ファイルが、PDBアーカイブで公開されました。
