Abstract: A strategy to functionally cure AIDS by eliminating latent HIV-1 reservoirs involves non-nucleoside reverse transcriptase inhibitors (NNRTIs) that promote pyroptosis of HIV-1 infected cells. These ...A strategy to functionally cure AIDS by eliminating latent HIV-1 reservoirs involves non-nucleoside reverse transcriptase inhibitors (NNRTIs) that promote pyroptosis of HIV-1 infected cells. These NNRTIs stimulate dimerization of the Gag-Pol polyprotein, resulting in premature HIV-1 protease (PR) dimerization and cleavage of intracellular CARD8. A unique cell-based high-throughput screen was developed to identify potent compounds activating the CARD8 inflammasome through Gag-Pol dimerization. Our in-house library of NNRTIs was evaluated, including a series of catechol diethers, which are potent, nontoxic antivirals. JLJ648 was identified as a promising dual-function antiviral and Gag-Pol dimerizer. Cryo-EM studies of HIV reverse transcriptase p66 bound to JLJ648 revealed populations of homodimers and, surprisingly, a homotetramer. This novel homotetramer structure resembling an 'infinity knot' revealed two JLJ648-bound homodimers forming an extensive interface and nucleated around a dimer of JLJ648 molecules. Structure-guided mutagenesis studies indicate that Gag-Pol homotetramerization may play a critical role in facilitating PR self-cleavage and triggering pyroptosis.

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.

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.
