Title: Characterization of Fully Recombinant Human 20S and 20S-PA200 Proteasome Complexes.
Authors: Ana Toste Rêgo / Paula C A da Fonseca /
Abstract: Proteasomes are essential in all eukaryotic cells. However, their function and regulation remain considerably elusive, particularly those of less abundant variants. We demonstrate the human 20S ...Proteasomes are essential in all eukaryotic cells. However, their function and regulation remain considerably elusive, particularly those of less abundant variants. We demonstrate the human 20S proteasome recombinant assembly and confirmed the recombinant complex integrity biochemically and with a 2.6 Å resolution cryo-EM map. To assess its competence to form higher-order assemblies, we prepared and analyzed recombinant human 20S-PA200, a poorly characterized nuclear complex. Its 3.0 Å resolution cryo-EM structure reveals the PA200 unique architecture; the details of its intricate interactions with the proteasome, resulting in unparalleled proteasome α ring rearrangements; and the molecular basis for PA200 allosteric modulation of the proteasome active sites. Non-protein cryo-EM densities could be assigned to PA200-bound inositol phosphates, and we speculate regarding their functional role. Here we open extensive opportunities to study the fundamental properties of the diverse and distinct eukaryotic proteasome variants and to improve proteasome targeting under different therapeutic conditions.

Initial modelPDB ID:

5le5


Chain - Source name: PDB / Chain - Initial model type: experimental model
DetailsThe model of the human recombinant 20S proteasome was built based on PDB: 5LE5 using real-space refinement in Coot and Phenix

Atomic model buiding 2

Detailsthe model for the human PA200 derived from Phyre2 and I-Tasser. These PA200 models were used as initial guides for the assignment of secondary structure using real-space refinement in Coot and Phenix, followed by correction of the sequence register using the amino acid side chain densities clearly resolved in our cryo-EM map. Connecting loops and all other regions were built ab initio from the cryo-EM density.

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.
