Hi,

If you checked the Ramachandran plot using PROCHECK, you may think
almost all residues belong to the most favoured, additional allowed,
or generously allowed regions of the Ramachandran plot that is the
part 1 of the PROCHECK output PostScript file.

But if you checked the part 2 of the PROCHECK output PostScript file
(Ramachandran plot by residue), you may find some unfavourable
conformations.  You can get the similar results as our validation
letter.


Please be informed that since August 1, 2007 we do not use PROCHECK
values for the definition of the Ramachandran outliers.
We define the Ramachandran outliers according to the following
reference:

GJ Kleywegt and TA Jones (1996). Phi/psi-chology: Ramachandran
revisited. Structure 4, 1395 - 1400

As mentioned in the validation report.

An additional information is available in the following website:

If you want to check your coordinate before deposition, please use our
validation server.
http://deposit.pdb.org/validate/
http://pdbdep.protein.osaka-u.ac.jp/validate/

In the validation summary letter that is in the result page of our
validation server, many of what we ask to depositors are written.


Thanks,
