Title: Architecture remodeling activates the HerA-DUF anti-phage defense system.

Guided by structure-based ...Leveraging AlphaFold models and integrated experiments, we characterized the HerA-DUF4297 (DUF) anti-phage defense system, focusing on DUF's undefined biochemical functions. Guided by structure-based genomic analyses, we found DUF homologs to be universally distributed across diverse bacterial immune systems. Notably, one such homolog, Cap4, is a nuclease. Inspired by this evolutionary clue, we tested DUF's nuclease activity and observed that DUF cleaves DNA substrates only when bound to its partner protein HerA. To dissect the mechanism of DUF activation, we determined the structures of DUF and HerA-DUF. Although DUF forms large oligomeric assemblies both alone and with HerA, oligomerization alone was insufficient to elicit nuclease activity. Instead, HerA binding induces a profound architecture remodeling that propagates throughout the complex. This remodeling reconfigures DUF into an active nuclease capable of robust DNA cleavage. Together, we highlight an architecture remodeling-driven mechanism that may inform the activation of other immune systems.

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.

Thousand views of thousand structures

  • Yorodumi is a browser for structure data from EMDB, PDB, SASBDB, etc.
  • This page is also the successor to EM Navigator detail page, and also detail information page/front-end page for Omokage search.
  • The word "yorodu" (or yorozu) is an old Japanese word meaning "ten thousand". "mi" (miru) is to see.
