PDB-style files for SCOP domains

The ATOM and HETATM records corresponding to each SCOP domain have been collated into PDB-style coordinate files. Header and remark records with more information about the domain are also provided.

Access:

• The archive of all PDB-style files has been split into 4 parts because the file size exceeds 2 GB. To get all the PDB-style files for Astral 1.65, download part 1 (1 GB), part 2 (1.1 GB), part 3 (331.5 MB) and part 4 (102.7 MB). Parts 1 - 2 contain files in which the data (excluding the REMARK comments) have not changed since 1.63. Part 3 contains files in which the data and REMARK comments have both changed. Part 4 contains new files for domains in SCOP classes 8 and above. All files will unpack into a single directory.
  Bug fix: If you downloaded the files before 30 March 2004, you should also download an archive of files with bug fixes (3.3 MB) Several multi-chain files were incorrectly generated. This affected files in part 3 (above), as well as both selected subsets (below); all files have now been corrected.

• If you only need smaller subsets of these files, you can instead download archives containing the PDB-style files corresponding to our two most commonly requested genetic domain sequence subsets: the 40% ID filtered subset (358.5 MB) and the 95% ID filtered subset (618 MB).

• If you have a set of older PDB-style files, you may want to download only those files in which the data have changed. A list showing the last Astral version in which the data (not headers) in each PDB-style file was last updated is here: pdbstyle-updated-1.65.txt

• For direct access to all the files, click here.

• or use this form to retrieve the file for a single domain by either the SCOP sid or sun identifiers:
  
  the PDB-style file for SCOP domain (i.e. "d1dlwa_" or "14982")
  Output will be returned as plain text HTML chemical/x-pdb .

Notes:

• Domains in the file hierarchy are named according to SCOP sid ID, not Astral ID, in cases where they are different (multi-chain domains begin with "g" or "e" in Astral and "d" in SCOP). Either ID will work in the above form, as well as the numeric sun IDs from SCOP.

• For domains containing multiple chains, the chains are ordered in the genetic domain order (as is the case for the sequences), not the order in the original PDB file. For example, chain B: may appear before chain A:

• For entries containing multiple models, all models are included, along with MODEL and ENDMDL records.

• We have inserted a TER record for each chain, and an END record at the end of the file.

• The header and remark records take the following form:
