Problem with HADDOCK (multiple forms of the same residue)

HADDOCK
1

Hi everyone,

I’m working on predicting protein-protein interaction (6YI3 of SARS-CoV and 1ZJK of MASP2) and cannot submit my job because of following error:

  • With the 1ZJK pdb file, it said:
    "Issue when parsing the PDB file at line 2743 .
    Your PDB contains multiple forms of the same residue MET 586 . This is not supported in the current form. If you would like to supply multiple conformations, please create an ensemble.

ATOM 2179 CE AMET A 586 13.656 -14.153 25.422 0.50 26.69 C (Offending Line) <–
ATOM 32 N ARG 3 11.281 86.699 94.383 0.50 35.88 N (Example Valid Line)"

  • I tried pdb_selaltloc.py but it didn’t work.

  • I used HADDOCK 2.4 server.

Please could you guys help me out with this. Many thanks for your time and kindness.

Define “it didn’t work…”

You can also try our now pdbtools server at: wenmr.science.uu.nl/pdbtools

Thank you very much. It works.
By the way, when I submit the job, there is a missing residue in the fixed file (that I let it automatically added by HIS). Should I do it that way or manually modify it ?
Again, many thanks for your kind support.

Be more specific if you want an answer…

What kind of residue?
