- general URL (language is automatically determined)
http://pdbj.org/pdb/1nih - Japanese page
http://pdbj.org/pdbj/1nih
5-5) Why is "j" written in lowercase while "J" of Japan is written in uppercase?
A) PDBj ( P rotein D ata B ank J apan) maintains a centralized PDB archive of macromolecular structures as a member of the wwPDB collaborating with the RCSB, the BMRB in USA and the PDBe in EU.
To emphasize PDB which is written in uppercase, we write a site identification character, the last j, in lowercase.
[Back to Questions]5-6) How can I uncompress gz file(.gz) on Windows? How can I compress a file into gz format on Windows?

(Host name) | |
PDBj FTP Server (incl. PDB Archive): | ftp.pdbj.org |
6-2) jV: RasMac does not recognize PDB files.
A) It is possible that RasMac has a bug on recognizing data format.
To avoid this problem, change the extension of the file from .pdb to .txt or relate the .pdb file
to RasMac.
You can use jV, an interactive 3D viewer program to visualize protein and nucleic acid molecules, which has been developed and updated by PDBj. Please see Installation of jV3 page.
[Back to Questions]6-3) jV: I have a problem displaying a PDB structure using PDBjViewer. What can I do?
A) PDBj Viewer is the old version of jV. Please install the latest version of jV.
[Back to Questions]6-4) jV: I encounter an error when using jV applet to view a structure.
A) When you use JRE6 Update15 (1.6.0_15) or JRE6 Update16 (1.6.0_16) on Windows or Linux, jV applet and applet-launcher fails to start up with the following error.
Error:java.io.IOException:Cannot find certificates for JNLP AppletLauncher class

In fact, your incomplete session is saved for a limit of 6 months from when it is first started.
7-4) When will an HPUB structure be released? The primary citation has been published.
A) We would appreciate it if you could provide the publication information from the Contact Us page.
The structure will be released the next Wednesday at 9 a.m.(JST) at the earliest, otherwise, on
the Wednesday of the following week.
7-6) What is the rule for assigning chain IDs? How are upper case letters, lower case letters and numbers used?
A) Please refer to 4 Chain ID assignment of Processing Procedures manual at http://www.wwpdb.org/docs.html.
Upper case letters and numbers should be used first for chain IDs. Lower case letters should be used only after all upper letters and numbers 0-9 have been used. In this way, a maximum of 62 chains can be included in the PDB entry. Other symbols should never be used for chain IDs.
[Back to Questions]7-7) Can I release my PDB entry (deposited as HPUB/HOLD) right away?
A) PDB entries can always be released at depositors request once annotation is complete .
Please contact the PDBj deposition and annotation staff using this form.
