Title: Structure and genome release of Twort-like Myoviridae phage with a double-layered baseplate.

Abstract: Bacteriophages from the family Myoviridae use double-layered contractile tails to infect bacteria. Contraction of the tail sheath enables the tail tube to penetrate through the bacterial cell wall ...Bacteriophages from the family Myoviridae use double-layered contractile tails to infect bacteria. Contraction of the tail sheath enables the tail tube to penetrate through the bacterial cell wall and serve as a channel for the transport of the phage genome into the cytoplasm. However, the mechanisms controlling the tail contraction and genome release of phages with "double-layered" baseplates were unknown. We used cryo-electron microscopy to show that the binding of the Twort-like phage phi812 to the Staphylococcus aureus cell wall requires a 210° rotation of the heterohexameric receptor-binding and tripod protein complexes within its baseplate about an axis perpendicular to the sixfold axis of the tail. This rotation reorients the receptor-binding proteins to point away from the phage head, and also results in disruption of the interaction of the tripod proteins with the tail sheath, hence triggering its contraction. However, the tail sheath contraction of Myoviridae phages is not sufficient to induce genome ejection. We show that the end of the phi812 double-stranded DNA genome is bound to one protein subunit from a connector complex that also forms an interface between the phage head and tail. The tail sheath contraction induces conformational changes of the neck and connector that result in disruption of the DNA binding. The genome penetrates into the neck, but is stopped at a bottleneck before the tail tube. A subsequent structural change of the tail tube induced by its interaction with the S. aureus cell is required for the genome's release.

Jan 31, 2019. EMDB accession codes are about to change! (news from PDBe EMDB page)

EMDB accession codes are about to change! (news from PDBe EMDB page)

  • The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
  • The EM Navigator/Yorodumi systems omit the EMD- prefix.
