Abstract: Serine hydroxymethyltransferase (SHMT) is a conserved enzyme in folate-mediated one-carbon metabolism, where it contributes to nucleotide biosynthesis, methylation capacity, and cellular stress ...Serine hydroxymethyltransferase (SHMT) is a conserved enzyme in folate-mediated one-carbon metabolism, where it contributes to nucleotide biosynthesis, methylation capacity, and cellular stress responses. Amino acid polymorphisms of soybean SHMT8 are known to affect the resistance of soybean to its primary pathogen, the soybean cyst nematode (SCN). A set of SHMT8 variants from ethyl methanesulfonate (EMS)-mutagenized soybean populations has been identified with varying resistance phenotypes, but their biochemical consequences remain poorly understood. Here, we use biochemical and structural studies to assess the impacts of the A149T variant on soybean SHMT8. Despite the conservative nature of the substitution, A149T reduces folate binding, pyridoxal-5'-phosphate-dependent catalysis, and thermal stability. High-resolution crystal structures (1.9-2.3 Å resolution) reveal only very minor structural changes. However, while the usual tetrameric assembly of the enzyme is retained at the high protein concentration in crystals, multiple other methods including a 2.9 Å cryo-electron microscopy (cryo-EM) structure show that the A149T variant is predominantly a dimer. Significant structural changes in the dimer are consistent with the observed biochemical impacts of the variant and help explain the well-known reduction in activity associated with dimerization of SHMT in other systems. We also find destabilization of the tetrameric assembly in other SHMT8 variants associated with changes in SCN resistance, suggesting that weakened oligomerization may be a common consequence of such mutations. Together, these results highlight quaternary structure as a critical determinant of SHMT8 activity and stability and suggest a potential mechanistic link between enzyme biochemistry and soybean defense.

Title: Macromolecular structure determination using X-rays, neutrons and electrons: recent developments in Phenix.

Abstract: Diffraction (X-ray, neutron and electron) and electron cryo-microscopy are powerful methods to determine three-dimensional macromolecular structures, which are required to understand biological ...Diffraction (X-ray, neutron and electron) and electron cryo-microscopy are powerful methods to determine three-dimensional macromolecular structures, which are required to understand biological processes and to develop new therapeutics against diseases. The overall structure-solution workflow is similar for these techniques, but nuances exist because the properties of the reduced experimental data are different. Software tools for structure determination should therefore be tailored for each method. Phenix is a comprehensive software package for macromolecular structure determination that handles data from any of these techniques. Tasks performed with Phenix include data-quality assessment, map improvement, model building, the validation/rebuilding/refinement cycle and deposition. Each tool caters to the type of experimental data. The design of Phenix emphasizes the automation of procedures, where possible, to minimize repetitive and time-consuming manual tasks, while default parameters are chosen to encourage best practice. A graphical user interface provides access to many command-line features of Phenix and streamlines the transition between programs, project tracking and re-running of previous tasks.

DetailsThe ASU contains 6 chains (A,B,C,D,E,F), where the chains A, B, C and D forms the tetramer in the ASU while chains E and F forms tetramers with their symmetry operators, out of the ASU. This mutant datasets show sever tNCS and always have very poor density for chain F. Hence we have left it out and did not build in the chain.

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.
