Description
The following bug report has been submitted:
Platform: macOS-15.4.1-x86_64-i386-64bit
ChimeraX Version: 1.10.dev202504250629 (2025-04-25 06:29:14 UTC)
Description
Special residues like phosphotyrosine or phosphoserine are not shown correctly in ChimeraX daily. This issue also extends to molecular dynamics definitions of residues like Histidine. PTR (or SEP/HIP/HIE) is shown with backbone broken. Please see the screenshot attached.
These problems are not present in the stable release.

Hi Mukundan,
Thanks for reporting this problem. I think I will need your PDB file in order to reproduce it. For instance, when I open 1AD5 in PDB format ("open 1ad5 for pdb"), the ribbon depiction at the PTR residues is continuous -- there is no break, so I would need your PDB file in order to find out why the ribbon for your structure behaves differently.

Hi Eric,
I have sent you the PDB file by email. Please let me know if you need additional information.
Best wishes,
Mukundan.

The PDB file was helpful and I have fixed the problem. PDB files generated by programs typically don't produce file that completely follow the PDB standard, so ChimeraX's PDB-reading code has a lot of special cases to try to handle all the variants correctly. A recent change to handle a peculiarity of MODELLER PDB files broke the reading of your file. Now I think both are handled correctly.
Fix: https://github.com/RBVI/ChimeraX/commit/093c63af7ff549a2e3a767d0804772be64a7fcc4
comment:5 by , 6 months ago
I tested with the May 6 daily build and can confirm that my PDB files are displayed are expected. Thank you for the quick fix. ________________________________ Email Disclaimer: www.stjude.org/emaildisclaimer Consultation Disclaimer: www.stjude.org/consultationdisclaimer
