Author Topic: strange residue number after dssr --view option (Read 20910 times)

shuxiang · « **on:** August 06, 2018, 01:10:13 pm »

Hi Xiang-Jun,

I'm using the following command to convert a DNA\protein structure into its best view conformation. (3mgp.cif is downloaded from PDB database).

x3dna-dssr -i=3mgp.cif -o=3mgp_view.cif --view

The weird thing is the residue number index of the DNA part from original file (3mgp.cif) is from 1 to 147. However, the corresponding residue number index from best view file (3mgp_view.cif) is from -73 to 73. I'm wondering is there an opinion to keep the residue renumber same between the original file and dssr output file? Thank you.

For example, the beginning DNA part of 3mgp.cif is:

Hi Shuxiang,

You've touched a subtle point in the labeling of residues (nucleotides) in mmCIF vs. PDB. Using PDB entry 3mgp, as you used, as an example, an excerpt for the corresponding PDB and mmCIF files (all downloaded from RCSB PDB) for I.DA.-73 is as below:

# PDB format

ATOM   6169  N  N9    . DA  I  5 1   ? 2.097   -4.257  94.106 1.00 167.70 ? -73  DA  I N9    1

As noted in the mmCIF header, the sequence number "-73" matches "_atom_site.auth_seq_id", and number "1" matches "_atom_site.label_seq_id". Since the corresponding PDB entry uses _atom_site.auth_seq_id (-73), DSSR follows that convention.

DSSR currently has no option to employ the labeling "_atom_site.label_seq_id" while "_atom_site.auth_seq_id" exists.

Best regards,

Xiang-Jun

Hi Xiang-Jun,

Thank you very much for your explanation. I will fix the server to correctly represent these structures (such as 3mgp) with conflicts between "_atom_site.label_seq_id" and "_atom_site.auth_seq_id".
