THE FIRST SEVEN MOLECULES WERE MODELED AS PHOSPHATIDYLCHOLINE WITH AN ALTERNATE CONFORMATION FOR ONE OF THE ACYL CHAINS IN MOLECULES 1 AND 5. MOLECULES 2-7 WERE MODELED AS UNKNOWN PHOSPHOLIPID BUT ARBITARILY CALLED PHOSPHATIDYLCHOLINE. ADDITIONAL 43 METHYLENE CHAIN FRAGMENTS WITH BETWEEN 20 AND 5 CARBON ATOMS EACH WERE MODELED. THREE OF THE HYDROCARBON SEGMENTS ARE BRANCHED BUT NOT MODELED AS PHOSPHOLIPID BECAUSE IT WAS IMPOSSIBLE TO IDENTIFY WHICH PORTION OF ELECTRON DENSITY BELONGED TO THE ACYL CHAINS AND POLAR HEADGROUPS. THE 43 MOLECULES NAMED UPL (ARBITARILY CALLED UNKNOWN BRANCHED PHOSPHOLIPID FRAGMENT) WAS SIMPLY MEANT TO REPRESENTS METHYLENE CHAIN FRAGMENTS.

PRECISE CLEAVED LENGTHS OF FRAGMENTS LV-1N, LV-1C AND LV-2 ARE NOT KNOWN. BOTH LV-1N AND LV-1C ARE PRESENTED HERE AS SINGLE ENTITY WITH CHAIN A TO CORRESSPOND WITH HOMOGENEOUS SINGLE POLYPEPTIDE IN LIPOVITELLINS OF OTHER SPECIES. ONE OF THE FRAGMENTS, PHOVITIN CONSISTING OF 232 RESIDUES (1074-1305) IN THE SWS ENTRY WAS PRESENT IN THE CRYSTAL BUT NONE OF ITS RESIDUE COULD BE MODELED DUE TO LACK OF ELECTRON 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.
