Abstract: Drug-resistant tuberculosis (TB) continues to challenge treatment options, necessitating the exploration of new compounds of novel targets. The mycobacterial respiratory complex cytochrome bc:aa has ...Drug-resistant tuberculosis (TB) continues to challenge treatment options, necessitating the exploration of new compounds of novel targets. The mycobacterial respiratory complex cytochrome bc:aa has emerged as a promising target, exemplified by the success of first-in-class inhibitor Q203 in phase 2 clinical trials. However, to fully exploit the potential of this target and to identify the best-in-class inhibitor more compounds need evaluation. Here, we introduce JNJ-2901, a novel Q203 analogue, that demonstrates activity against multidrug-resistant clinical strains at sub-nanomolar concentration and 4-log reduction in bacterial burden in a mouse model of TB infection. Inhibitory studies on purified enzymes validate the nanomolar inhibitions observed in mycobacterial cells. Additionally, cryo-EM structure analysis of cytochrome bc:aa bound to JNJ-2901 reveals the binding pocket at the menaquinol oxidation site (Qp), akin to other substate analogue inhibitors like Q203 and TB47. Validation of the binding site is further achieved by generating and isolating the JNJ-2901 resistant mutations in , followed by purification and resistance analysis of the resistant cytochrome bc:aa complex. Our comprehensive work lays the foundation for further clinical validations of JNJ-2901.

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.

Yorodumi

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.
