wwPDBAC 2007 Recommendations

• Structure factors and/or NMR restraints should be
  a prerequisite for receiving a PDB ID
• Done
• Inform the relevant journals of this new policy
• Done adopted by some but not all
• Validation
• Establish additional X-ray crystallography and
  NMR validation procedures
• In progress
• Results should be made available to depositors
  immediately after submission. Upon depositor
  request, the validation reports should be made
  available to designated scientific journal
  editors
• Possible now, journal policies have not as yet
  changed
• Work to establish recommendations for additional
  experimental data deposition and release
  requirements
• In progress

Simultaneous weekly update of PDB archive

• In the past, PDBj site started to copy the latest
  data and load them to the local database system
  only after the RCSB-PDB archive was updated on
  Wednesday. Therefore, there was some delay in
  updating the database at PDBj. This frustrated
  potential PDBj users and they preferred to access
  RCSB-PDB.
• From Sept. 2008, PDBj copies the latest data
  directly from the internal database in RCSB-PDB
  to pre-construct the PDBj database on Saturday
  midnight.
• By receiving a mail sent from RCSB-PDB
  automatically after updating the public ftp-site
  on every Wednesday, the ftp-site at PDBj is also
  updated with little time delay.

NMR Update
Worldwide Protein Data Bank www.wwpdb.org

• John Markley

22
NMR structure depositions

• Number of NMR structures deposited through
  ADIT-NMR (09/01/07-08/31/08)
• BMRB -gt RCSB PDB 461
• PDBj - BMRB -gt PDBj 112
• Restraints remediation
• Processing is virtually complete
• Will be released as soon as it can be made
  consistent with the remediated chemical
  components dictionary

23
wwPDB policies and rules on NMR entries

• Two types of NMR experiments will be
  distinguished in the PDB entries
• Solution NMR
• Solid-state NMR
• NMR entries will have new PDB records
• MDLTYP to indicate MINIMIZED AVERAGE
• NUMMDL to specify number of models in entry
• These changes are reflected in Format Guide 3.2
  

24
wwPDB policies and rules on NMR entries

• The numbering of models is sequential, beginning
  with 1
• All models in a deposition (ensemble members and
  minimized average, if provided) should be
  superimposed in an appropriate author determined
  manner, and only one superposition method should
  be used.
• All models in an NMR ensemble and the minimized
  average structure, if provided, should have the
  same sequence and covalent structure (exact same
  number and type of atoms hydrogens and heavy
  atoms), and chemistry (e.g., protonation state)

25
Policies clarified by NMR Task Force August 26,
2008

• PDB will accept minimized average structures only
  if they meet the above criteria for alignment and
  covalent structure
• The number of models will not be limited in a PDB
  file
• Chemical shifts deposition will become mandatory
• Depositors are encouraged to avail themselves of
  third-party validation software prior to
  deposition of NMR structures

PDB Contents Guide Version 3.2

• The goal was to further clarify all formats and
  procedures so as to create a more uniform archive

29

  correctness and clarity by wwPDB annotators
• Some records were added and others expanded
• Task Force members were consulted where
  appropriate

wwPDB Validation Task Force
This meeting of the X-ray Validation Task Force
was held to collect recommendations and develop
consensus on additional validation that should be
performed on PDB entries, and to identify
software applications to perform validation tasks.
Preliminary Outcomes

• Workshop report to be published in Fall 2008
• Candidate global and local validation measures
  were identified
• These measures were reviewed in terms of the
  requirements of depositors, reviewers, and users

35
Remediation and Curation of Complex Chemistry in
the PDB
36
SCOPE

• Inhibitor molecules annotate the chem comp
  dictionary and migrate details to PDB entries
• Ribosomal (postranslational modifications) and
  non-ribosomal cyclic, modified and conjugated
  peptides consistently given a SEQRES , SOURCE
  annotate an entity look up table and transfer to
  PDB entries

Value to users

• To understand unique and shared aspects of a
  particular occurrence
• To find a specific system Some components of a
  PDB file, such as inhibitors and antibiotic
  peptides, might not be found or even be apparent
  
• To study related ligands across different
  proteins

41
Challenges

• Inclusion of non-standard amino acid,
  nucleotides, or other chemical groups in sequence
• Non-linear (cyclic or branched) sequences
• Microheterogeneity (some cases)
• Non-uniform annotation of the same molecule in
  different PDB entries
• Lack of annotation regarding the source and
  function of these molecules

42
Solutions

• Analysis and classification
• Identify antibiotics and inhibitors and group
  them into polymeric molecules or single
  components
• Dictionary updates
• Build single chemical components for appropriate
  cases
• Update dictionary with source, function and other
  details
• Remediation and future processing
• Edit/revise files to include compound name,
  sequence, source and function for all antibiotics
  and inhibitors
• Establish rules and procedures to make new
  annotations consistent

43
Single component vs. Polymeric

• Single component antibiotics or inhibitors
• Build component and retain subcomponent
  information annotate dictionary with details
  about molecule
• Migrate details from dictionary to entry files in
  specific remarks
• e.g. D-Phenylalanyl-L-prolyl-L-arginine
  chloromethyl ketone (PPACK)
• Polymeric (peptide-like) antibiotics or
  inhibitors
• Present sequence, compound name, and source
  information as any regular polymer
• Include details about functions in specific
  remarks
• e.g. post-translationally modified ribosomal
  peptides, non-ribosomal cyclic, modified or
  conjugated peptides

THIOSTREPTON
_entity.pdbx_description Thiostrepton complex
bacterial natural product containing thiazole
rings that's used as a topical veterinary
antibiotic and also has promising antimalarial
and anticancer activity first isolated from
bacteria in 1955, thiostrepton has an unusual
type of antibiotic activity It disables protein
biosynthesis by binding to ribosomal RNA and one
of its associated proteins and interacts directly
with 23S rRNA nucleotides 1067A and
1095A _entity.type Polypeptide, sulfur
containing antibiotic _entity.details
Thiostrepton is a macrocyclic antibiotic
incorporating thiazoles and other atypical amino
acids. Patented in 1961, thiostrepton has been
used as an antibiotic and acts by binding to
ribosomes to prevent the binding of the EF-G
elongation factor and GTP to the 50S riobsomal
subunit. Thiostrepton is an inducer of tipA, a
gene that controls the bacterial transcription
regulators, TipAL and TipAS, members of the MerR
proteins that are central regulators in multidrug
resistance. Closely related to siomycin, a
recently discovered inhibitor of oncogenic
transcription factor - FoxM1. The
thiostrepton-resistant gene is also commonly used
as a selective marker for recombinant DNA/plasmid
technologies.

  and eliminate individual points of failure
• Will implement recommendations of NMR and X-ray
  Validation Task Forces
• Will allow for data acquisition of coordinate,
  experimental and meta data for all methods
• Will ensure quality, consistency and efficiency
  of data processing and annotation process

59
Assumptions

• The deposition tools must be able to handle all
  current, agreed upon, data entry formats from the
  user community
• The underlying system design will not be driven
  by existing formats
• The product must provide an extensible framework
  enabling support for new experimental methods
  over its ten year life span
• The project technical level will be set at a
  reasonable standard. Technology should not be
  bleeding edge nor declining.
