Components

#1: Protein Calcium-binding EF hand family protein / F2D10.25


Mass: 11736.118 Da / Num. of mol.: 1
Source method: isolated from a genetically manipulated source
Details: The first 21 amino acids encode for an N-terminal 6xHis tag and a TEV cleavage site. The protein was subjected to a TEV digest hence the first 15 amino acids should no longer be present.
Source: (gene. exp.) Arabidopsis thaliana (thale cress) / Gene: At1g20760, F2D10.25, F2D10_25 / Plasmid: pEt22b / Production host: Escherichia coli BL21(DE3) (bacteria) / Variant (production host): NEB C2527 / References: UniProt: Q9LM78

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.
