How to insert a nucleotide to a pdb
Hi,
I have a pdb-file of the ribosome and would like to insert two nucleotides to one of the rRNA-chains. How do I do that? I’ve found the addaa command for amino acids, is there a similar one for nucleotides?
Best regards, Magdalena

Hi Magdalena, Sorry, there is no command to add a nucleotide residue on the end of a nucleotide chain.
You could still try to do this in Chimera, but it may be tricky and have several steps:
(1) find another PDB structure that has those two residues, then open it, delete all the rest of that structure - OR - use the Start Structure section of the Build Structure tool (in menu under Tools... Structure Editing) to build the dinucleotide. This will only build helical conformations, however.
(2) use the Join Models section in the Build Structure tool to combine and bond the 2 residues into your original structure.
It may be hard to get the right angles/position, so you may have to rotate some bonds after that (see Adjust Torsions section of the Build Structure tool).
Click the Help button on the Build Structure tool for details, or see the copy of the same information at our website: https://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/editing/editing.html

Hi Elaine,
Thanks a lot for your answer.
I actually want to insert the nucleotides into the middle of an RNA sequence. Then that gets even trickier I guess?
Cheers, Magdalena

Dear all, is there a way in Chimera or ChimeraX to get the unit-cell box being drawn in another colour than white? This forces the background to be dark.... Thanks a lot in advance, Xavier

Dear Elaine, I am now trying to get this done in ChimeraX where there is indeed a similar option. Unfortunately, if I proceed as in the instructions I do not get the cell box, in contrast with old Chimera. I also tried through the command line but unsuccessfully. Am I missing something? Thanks a lot in advance, Xavier

Hi Xavier, As far as I can tell, it is exactly the same in ChimeraX as in Chimera. First, make sure you aren't using a very old version of ChimeraX. I tried it in ChimeraX 1.5 release candidate (2022-11-08) just now:
- open your structure that has unit cell information, e.g. 1fav
- in Unit Cell tool (menu: Tools... Higher-Order Structure... Unit Cell) click Outline to show unit cell box
- if you want to change box outline color, can use the same method as described below for Chimera. I wasn't able to select it by Ctrl-click, however, so instead use the selection (hand with green dot) checkbox in the Model Panel to select it, then use Actions... Color... [...]. Or, you can just click the color square in the Model Panel and use the system color chooser to change the color interactively. Screenshot:

Thanks a lot, Elaine, this worked indeed! Just one final point: how can I make the linewidth larger? When I make a picture, the thin lines of the box disappear. I understand ChimeraX interpretes these lines as a surface, I can change the colour when choosing surface in the colour blow up.

(switching to chimerax-users address since this is all about ChimeraX, not Chimera)
Sorry no, there is no linewidth setting on the unit cell outline box.
However, you can "fake it" by selecting that model so that there are green outlines to show the selection, and then changing the selection-outline color and width:
(1) select the outline box model, e.g. as described in the previous message by checking the selection box in the Model Panel
(2) use "graphics selection" command to change the selection-outline color and thickness https://rbvi.ucsf.edu/chimerax/docs/user/commands/graphics.html#selection

Hi Magdalena, Chimera does not include tools to insert nucleotides in the middle of a chain.
However, take a look at the RNArtist program for RNA modeling -- it has a lot of fancy features and interfaces with Chimera (or ChimeraX) for the display: https://github.com/fjossinet/RNArtist
There is also the program Assemble2 by the same author, also works with Chimera: https://www.rbvi.ucsf.edu/chimera/plugins/plugins.html#assemble2 http://bioinformatics.org/assemble/index.html
