recommendations
15Simultaneous 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.

22NMR 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
23wwPDB 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
24wwPDB 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)
25Policies 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
26Improvements in Data Deposition and Annotation
Worldwide Protein Data Bank www.wwpdb.org
27A year of VTCs and discussions
28PDB Contents Guide Version 3.2
- The goal was to further clarify all formats and
procedures so as to create a more uniform archive
29Process
- Every record was reviewed for scientific
correctness and clarity by wwPDB annotators - Some records were added and others expanded
- Task Force members were consulted where
appropriate
30Added PDB Format Records
SPLIT for large structures to indicate number of
PDB entries NUMMDL number of MODELS in an

34wwPDB 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
35Remediation and Curation of Complex Chemistry in
the PDB
36SCOPE
- 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

40Value 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
41Challenges
- 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
42Solutions
- 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
43Single 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

47THIOSTREPTON
_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.

55New Projects
Worldwide Protein Data Bank www.wwpdb.org
56Small Angle Scattering
- Two-member annotator team reviewing possible SAXS
and SANS templates - Attendance at SAS Commission to discuss
deposition and publication requirements - Template recommendation expected in 2009
57Common Deposition and Annotation Tool
- Selected as the most important project going
forward by participants of the 2007 wwPDB Retreat - Project timeline Concept in 2008, design and
development 2009 - 2011 with delivery by 2012 - Progress
- wwPDB Directors adopted role of Steering
Committee and initiated the project Concept Phase - Concept Team, representing the 4 partner sites,
meet to create Scope Document (December 2008) - Steering Committee approved the Scope Document in
May 2008 - Core Team Kick Off meeting July 2008
58Scope
- wwPDB-wide project
- Will allow full sharing of data load worldwide
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
59Assumptions
- 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.
60Core Team Kick Off
61Core Team Meeting Outcome

project - Draft a conceptual design for the solution and
identify critical components that need to be
investigated - Identify the top three challenges and initiate
study groups - Future system data model (John Westbrook and Tom
Oldfield) - Technologies and strategies for data and
statemanagement (John Westbrook) - Technologies and strategies for automation of
