pdb_extract is a pre-deposition service for assembling structure files for wwPDB OneDep deposition .
Use this online tool (tutorials available)
or download the standalone program to run on your local machine. This tool will:
- Convert PDB format file to mmCIF format
- Prepare a re-usable template file of your metadata via PDBj's mmCIF Editor for Xray,
NMR,
EM
(*Note: click Editor's upper-left gear icon to save/download or access help). The template can be uploaded at the next step, and used for multiple entries.
- Assemble coordinates and log files pertaining to your specific experimental methods.
- Allow you to update the primary sequence of your protein/nucleotide chains to account for unresolved residues.
How to Run:
- Select the experimental method you used to solve the structure
- Select the type of structure model coordinates file to be uploaded
- Upload the finally refined structure model coordinate file
- Press the RUN button to start pdb_extract
- The mmCIF files that you obtain can be used as input for wwPDB OneDep deposition and
validation.
If you upload PDB format structure model coordinates file:
1. The column alignment for ATOM and/or HETATM record rows must be correct.
2. Please ensure that each polymer has a unique Chain ID in the file. If your uploaded file does not have chain ID, pdb_extract will try the best guess to add chain ID, and if so please review the chain ID addition on the next page.
3. A TER card must be present at the end of each complete polymer chain, but a TER card should not be placed in the middle of a polymer chain even if there is a main-chain break due to disordered residues not built in the model.
Note:
If the file size is too large (e.g. >100 MB), you can upload gzipped (
*.gz) or compressed (
*.Z) file for faster loading.
