Hello, This was described by Eric just yesterday: <https://mail.cgl.ucsf.edu/mailman/archives/list/chimerax-users@cgl.ucsf.edu/message/PTDGZ5MOD7A67FWUWNI2LNT6EVW3HOPJ/>

To summarize, you can use either of the following

(A) Build Structure tool. Select the alpha-carbon of an amino acid residue (hide ribbons and show atoms, Ctrl-click CA atom). Open the tool from the menu: Tools... Structure Editing... Build Structure, and in that tool change from the Start Structure section to the Invert section, then click "Swap" <https://rbvi.ucsf.edu/chimerax/docs/user/tools/buildstructure.html#invert>

(B) "build invert" command on the CA atom of an amino acid residue, for example residue 51 in chain A:

build invert /A:51@ca

<https://rbvi.ucsf.edu/chimerax/docs/user/commands/build.html#invert>

I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Hi everyone,

Is there any way of changing the isomerism of protein residues from L to D? I use ChimeraX with students and it would be great to see what happens with some features of the structure like hydrophobicity after changing isomers.

Thanks so much in advance
