8gpb - error at end
2hhr - end of chain c has extra residues in ATOM records
1ysa - chains c and d
2plv - seqres 76,97,98 in wrong place  
2psg - PO4 is misnumbered as seqres 112
1ltb - seqres too short; seqres 329 misplaced
1lta - seqres too short; seqres 329 misplaced
1aip - seqres 403-405 for chains a and b curiously missing
1bxt - chain A has no SEQRES in PDB file
1a35 - There is an ALA at 635 and at 712, and
       pdb2cif program guessed wrong and thought that the ALA in the
       file is the one at 712 (485 in SEQRES numbering) -- but it is
       really the one at 635 (461 in SEQRES numbering).
1dbh - ATOM residues 418-422 match SEQRES 221-225, but are not indicated
       as matching
