THE ...VANIPREVIR (MK-7009) IS A MACROCYCLIC, PEPTIDOMIMETIC HCV NS3/4A PROTEASE INHIBITOR FROM MERCK. THE DRUG MIMICS THE PEPTIDE BACKBONE OF PROTEINS, ALTHOUGH THE DRUG MOIETIES CANNOT BE SEQUENCED USING AMINO ACID NOMENCLATURE.
Sequence detailsTHE COFACTOR 4A RESIDUES 990-1000 (GLY SER VAL VAL ILE VAL GLY ARG ILE ASN LEU) IN THIS ENTRY ...THE COFACTOR 4A RESIDUES 990-1000 (GLY SER VAL VAL ILE VAL GLY ARG ILE ASN LEU) IN THIS ENTRY CORRESPOND TO RESIDUES NUMBERING 1678-1688 OF DATABASE SEQUENCE REFERENCE (UNP A8DG50). THIS PEPTIDE IS COVALENTLY LINKED TO THE N-TERMINUS OF NS3. C1679S MUTATION WAS ENGINEERED TO PREVENT DISULFIDE FORMATION. THE V1686I AND I1687N WERE ENGINEERED TO OPTIMIZE THE LINKER BETWEEN THE COFACTOR 4A AND NS3.

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.

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.
