Title: Cryo-EM structure of translesion DNA synthesis polymerase ζ with a base pair mismatch.
Authors: Radhika Malik / Robert E Johnson / Louise Prakash / Satya Prakash / Iban Ubarretxena-Belandia / Aneel K Aggarwal /
Abstract: The B-family multi-subunit DNA polymerase ζ (Polζ) is important for translesion DNA synthesis (TLS) during replication, due to its ability to extend synthesis past nucleotides opposite DNA lesions ...The B-family multi-subunit DNA polymerase ζ (Polζ) is important for translesion DNA synthesis (TLS) during replication, due to its ability to extend synthesis past nucleotides opposite DNA lesions and mismatched base pairs. We present a cryo-EM structure of Saccharomyces cerevisiae Polζ with an A:C mismatch at the primer terminus. The structure shows how the Polζ active site responds to the mismatched duplex DNA distortion, including the loosening of key protein-DNA interactions and a fingers domain in an "open" conformation, while the incoming dCTP is still able to bind for the extension reaction. The structure of the mismatched DNA-Polζ ternary complex reveals insights into mechanisms that either stall or favor continued DNA synthesis in eukaryotes.

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.

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.

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.
