Title: Structural basis of unisite catalysis of bacterial FF-ATPase.
Authors: Atsuki Nakano / Jun-Ichi Kishikawa / Atsuko Nakanishi / Kaoru Mitsuoka / Ken Yokoyama /
Abstract: Adenosine triphosphate (ATP) synthases (FF-ATPases) are crucial for all aerobic organisms. F, a water-soluble domain, can catalyze both the synthesis and hydrolysis of ATP with the rotation of the ...Adenosine triphosphate (ATP) synthases (FF-ATPases) are crucial for all aerobic organisms. F, a water-soluble domain, can catalyze both the synthesis and hydrolysis of ATP with the rotation of the central rotor inside a cylinder made of in three different conformations (referred to as , , and ). In this study, we determined multiple cryo-electron microscopy structures of bacterial FF exposed to different reaction conditions. The structures of nucleotide-depleted FF indicate that the ε subunit directly forces to adopt a closed form independent of the nucleotide binding to . The structure of FF under conditions that permit only a single catalytic subunit per enzyme to bind ATP is referred to as unisite catalysis and reveals that ATP hydrolysis unexpectedly occurs on instead of , where ATP hydrolysis proceeds in the steady-state catalysis of FF. This indicates that the unisite catalysis of bacterial FF significantly differs from the kinetics of steady-state turnover with continuous rotation of the shaft.

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.
