dealing with symmetrics
« on: June 17, 2013, 06:39:04 am »
Hi Xiang-Jun,

We are, besides regular interactions, also interested by interactions involving symmetric fragments.

As you perhaps know, pymol puts out PDB files with an additional four letter code (see below).
We are using this four letter code for expanding our evaluation of non-covalent interactions.

As such, could you eventually add an option to 3DNA and/or DSSR (like -sym) that would allow to differentiate original nucleotides from symmetric ones.

For example, see this PDB fragment generated by pymol from the 100D file.

HETATM  487  O   HOH B  77       1.829  -2.266   9.724  1.00 75.20           O 
HETATM  489  O   HOH B  79      -9.310  -1.446  19.391  1.00 71.79           O 
HETATM  411  N1  SPM A  21     -13.297  -8.783  22.839  1.00 40.13      AZ00 N 
HETATM  412  C2  SPM A  21     -12.449  -7.621  23.379  1.00 38.06      AZ00 C 
HETATM  413  C3  SPM A  21     -13.154  -6.312  23.033  1.00 36.69      AZ00 C 
HETATM  414  C4  SPM A  21     -12.226  -5.116  22.994  1.00 35.02      AZ00 C 

The four letter code is not something that is in the current PDB format but was allowed in previous versions.
In this example, it corresponds to a symmetry code that is specific to the used symmetry operations.

In DSSR, you could for example write:

  13 .A.DG.9.         .B.DC.12.*        G-C WC           19-XIX    cWW cW-W
Where the star indicates a symmetric.

You could also consider (better option)
  13 .A.DG.9.         .B.DC.12.1Z00        G-C WC           19-XIX    cWW cW-W
Where you would write the symmetric code in full.

This would be really greatly helpful to us.

Best,

Pascal

Could you provide (a link to) the full specification of the PyMOL-customerized PDB format with a complete example? I may consider to handle the extra symmetric fragment if the functionality fits the overall design of DSSR.

Xiang-Jun,

Thats good news.
Basically, pymol uses the segment identifier code defined here:

http://deposit.rcsb.org/adit/docs/pdb_atom_format.html

at the "Record: ATOM" line:
73 - 76        LString(4)      Segment identifier, left-justified.

See this example (A1  )
       
ATOM    145  N   VAL A  25      32.433  16.336  57.540  1.00 11.92      A1   N

or (AZ00)

HETATM  489  O   HOH B  79      -9.310  -1.446  19.391  1.00 71.79           O 
HETATM  411  N1  SPM A  21     -13.297  -8.783  22.839  1.00 40.13      AZ00 N

(sorry for the fact that I am unable to write these lines with an non-proportional font)

pymol uses these specifications.

Yet, this is an old pdb definition as you can judge from the most recent one
http://www.wwpdb.org/documentation/format33/sect9.html#ATOM
that does not mention a segment identifier.

Here is what I found in pymol documentation
---
“segment” selects atoms based on their assigned chain, which is a four-letter code.

A PyMOL Segment is a set of atoms within a single molecular object that share all property identifiers except atom names, residue and chain property identifiers.

Segments are most useful in cases where multiple copies of an identical set of chains must exist inside of a single molecular object. They also come in handy for complex proteins which have more chains than can represented with a single-character alphanumeric identifier.
---
Would be great if you could make this work,
Thanks for considering it,

Pascal

Okay, I got the idea, and I will take segid into consideration in the next release of DSSR.

To use fixed space font, you could try Tt button, # button for code, or pre-formatted text button -- all on the menu, in a similar fashion as in Word.

Ok, but I don't see it working on my screen. I tried !
I join a pdb file that contains segid and that was generated by pymol.
Any timeline for a new version ?

Weird. Then your settings are not the default. You can type the formatting BBcode manually, as below:

[tt]...[/tt]
[code]...[/code]
[pre]...[/pre]

Thanks for sample PDB file with segid.

It won't be long, hopefully. In the meantime, could you reply to my posts that address your previous requests?

Hi Pascal,

I've updated DSSR to beta-r13-on-20130618 which took into consideration of segid, among other refinements. Using your sample PDB file as an example, the output is as below:

Code: [Select]
Run: x3dna-dssr -i=100d.py.pdb -o=100d.py.out --long-idstr  --note=no

Hi Xiang-Jun,

I like your new version. Unfortunately, I think that I lost the
ability to include the PDB segID into the dssr out files
as you implemented it recently!

  28 .B000.B.G.20.    .CA00.B.DC.15.   G-C              00-n/a    cSS tm-m
       -147.2(anti) C3'-endo lambda=109.9; -152.0(anti) C2'-exo lambda=109.8
       d(C1'-C1')=5.30 d(N1-N9)=6.63 d(C6-C8)=8.75 tor(N1-C1'-C1'-N9)=95.6
       H-bonds[1]: "N2(amino)-O2(carbonyl)[3.10]"

I join two files in order for you to check if may be the pdb
file we used causes the problem.

Best,

Pascal

Hi Pascal,

Thanks for your following up. As of beta-r19-on-20130819, I have "removed the segid info from nucleotide id-string by default" (see the release note). As you already noticed, segid is not in PDB format v3, nor is it in PDBx/mmCIF. It thus makes sense to me to remove it from the DSSR default output, since it would empty in the majority of cases. However, you can get what to desire by specifying the --segid option explicitly.

HTH,

Hi Xiang-Jun,

The --segid option works fine. Just encountered a new exception with attached file and option combination. (I send you the pdb file by mail since its too large).

29858 Segmentation fault      (core dumped) x3dna-dssr --non-pair --long-idstr --hbond_d2=3.5 --po4 --u-turn --segid -i=/media/HD/DATA/pdb_files_temp/3F1E/3F1E.py.pdb -o=3F1E.py.dssr.out

Thanks for having a look,

Best,

Pascal

Hi Pascal,

I've updated DSSR to beta-r23-on-20130918 on the download page. Please verify and report back if it fixes the problem you experienced.

As a general rule, it helps that users follow up timely on a case-by-case basis rather than post back only when they have a new request or meet another problem.
