Mass spectrometry of purified protein shows that Palmitoyl-CoA copurifies with the EspE7-R35A protein during purification when expressed in E.coli. The CoA adduct seen in the electron density maps is disordered to varying degrees in the different pockets in the asymmetric unit. In one pocket, most of the Palmitoyl-CoA can be built with the Adenosine positioned in a less common position relative to other homologs with CoA adducts bound. This is likely due to packing constraints. In some symmetry copies, there is considerable disorder of the region beyond the diphosphate and the Adenosine was left unmodeled with some difference peaks that likely represent its multiple positions. Along the fatty acid chain, the density gets weaker as one goes further from the CoA and deeper into the binding pocket. Most chains have good density to around the C8-C10 position with not much density beyond C12. Building full length Palmitoyl tail in the pocket results in negative difference density for the terminal atoms. There is also clear disorder for the side-chain of Met-91 with one conformer blocking longer chain fatty acids in the pocket. In the end, the ligand was modeled as dodecyl-CoA (lauryl-CoA). The presumption is that there could be a mix of fatty acid chain lengths of coA adducts bound and co-purified. 3. The metal ion near the fatty acid chain was modeled as a potassium ion. The presence of an anomalous peak similar in height to sulfur atoms suggests it is heavier than Na or Mg. The height of this anomalous peak is unchanged when the data was re-collected above and below the Zn K-edge and below the iron K-edge, suggesting that the metal must be lighter than Fe. The lack of a signal for Mn in an X-ray fluorescence emission spectra suggests it is not Mn. The two most likely candidates from the anomalous and X-ray fluorescence experiments is Calcium and Potassium - both of which would have anomalous peaks at the energies used for data collection (12000, 9709, 9609 and 7000 eV) and also emit at an energy below where the beamline setup can detect in the emission spectra. Looking at the results of the geometric and valence sum criteria when modeled as Ca and K on the check my metal server, both options had several criteria that were supportive of the assignment and some that were marginal. In the end, K was selected as being slightly more favorable but the assignment is not definitive. 4. There are a large number of residues at the N- and C-termini that cannot be built due to disorder. The C-terminal region was predicted to be disordered. An extra 10 residues from chain B can be built as they are packed against a symmetry adjacent tetramer. In chain D, density for the C-terminus packing against a neighboring tetramer is also visible, but it is not ordered enough to reliably build. The N-terminal expression and purification tag cannot be built. There are a number of un-built difference map peaks along the surface of the protein that are likely protein residues from the C-terminus or N-terminus of symmetry adjacent tetramers, but it was not possible to build and identify the register of these residues.

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.

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.
