Thank you Dr. Mooers,

That worked! I’ve been trying to solve that for months. I’ve been able to get 
my protein, linker and actin to fuse.

I have now built a chain of five actin and I’m encountering another barrier. 
I’m attempting to link a protein to each actin, but the program recognizes all 
5 linkers as the same linker (all linkers have the same sequence). I’m trying 
to figure out how to give each linker its own separate name. I’ve searched the 
mailing group archive and looked at the Alter page you linked for the first 
solution, but can’t figure out what to do.

If you have any further advice that would be much appreciated!

Patricia

Hi Patricia,

You can copy and paste these commands below one at a time at the upper PyMOL> 
prompt just below the command history window.
Hit return after each paste operation.

alter (chain A),chain='F'
sort

Best regards,

Subject: [EXTERNAL] [PyMOL] Changing Chain ID

Hi – I’m a high school student learning to use Pymol for my science fair 
research, and I’ve been using Pymol for about 6 months. I have been working on 
attempting to bind a protein to actin for over a month now – but whenever I 
fuse the linker to the antifreeze protein, it glitches. As well, when I save my 
actin chain with all the linkers fused as a PDB file and reopen it, only one of 
the linkers is visible. I’m hoping you might be able to help me figure out what 
I’m doing wrong.

Schrodenger support provided a recommendation. Part of it is to rename the 
protein chain to something else (e.g., chain F) so that it wouldn't interfere 
with chain A from the F-Actin chain. I’ve been unable to figure out how to 
change the name/ID of my chains. I have tried changing to “3 Button Viewing”, 
selecting “Chains”, clicking on the chain of interest, clicking on the 
selection “A” action button and selecting “rename selection”, as well as using 
the "set_name" command, but neither are working.

Can anyone help me figure out what I’m doing wrong?

Thanks so much!
