PDB
Statistics
Which journal has published the most structures? What types of
structures have been solved by more than one experimental method?
Answers to these questions can be found by exploring the various
statistics about the data in the PDB archive available by clicking
the PDB Statistics link at the top of every page on the RCSB PDB
website. Charts, graphs, and tables related to content distribution
include:
- Summary Table of Released Entries: Current PDB holdings grouped
by experimental method and molecule type
- Status of Unreleased Entries: A pie chart that illustrates the
status of unreleased entries
- Interactive histograms showing the archive by function, resolution,
space group, source organism, journal, molecular weight, and enzyme
classification
- Histogram showing the number of structures solved by structural
genomics structures
- Table of proteins solved by multiple experimental methods
- Current statistics on redundancy in the archive
The growth in the number of structures released in the PDB archive
can be seen per year, by experimental method, and by molecule type.
Other graphs show the growth of unique protein classifications as
defined by SCOP (scop.mrc-lmb.cam.ac.uk/scop/index.html)
and CATH (cathwww.biochem.ucl.ac.uk).
Time-stamped
Copies of PDB Archive Available via FTP
A time-stamped snapshot of the PDB archive (ftp.wwpdb.org)
as of January 7, 2008 has been added to ftp://snapshots.rcsb.org/.
Snapshots of the PDB have been archived annually since 2004. It
is hoped that these snapshots will provide readily identifiable
data sets for research on the PDB archive.
The script at ftp://snapshots.rcsb.org/rsyncSnapshots.sh
may be used to make a local copy of a snapshot or sections of the
snapshot.
The directory 20080107 includes the 48,161 experimentally-determined
coordinate files that were current as of January 7, 2008. Coordinate
data are available in PDB, mmCIF, and XML formats. The date and
time stamp of each file indicates the last time the file was modified. |
