To combat multidrug-resistant bacteria, new antibacterial strategies are needed. In the peptidoglycan biogenesis pathway in , MurJ, the lipid II flippase, is an essential membrane protein. The 37-residue protein M from the phage, known as Lys or Sgl, targets MurJ and induces cell lysis; however, its molecular mechanism remains unclear. Here, we present the cryo-EM structure of the MurJ/Lys (JM) complex at 3.09-angstrom resolution, revealing that Lys interacts with the crevasse between TM2 and TM7 of MurJ, locking MurJ in an outward-facing conformation, with Lys acting like a wedge. Alanine-scanning mutagenesis and pull-down assays revealed key residues responsible for Lys function, and molecular dynamics simulations showed that Lys stabilizes MurJ's outward-facing state. These findings demonstrate an unprecedented phage-derived mechanism for blocking lipid II transport, providing a structural framework for designing MurJ-targeted antimicrobial agents.

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.

Jul 12, 2017. Major update of PDB

Major update of PDB

  • wwPDB released updated PDB data conforming to the new PDBx/mmCIF dictionary.
  • This is a major update changing the version number from 4 to 5, and with Remediation, in which all the entries are updated.
  • In this update, many items about electron microscopy experimental information are reorganized (e.g. em_software).
  • Now, EM Navigator and Yorodumi are based on the updated data.
