Hi Noor, No, swapaa cannot do that. However, you could use the "Build Structure" tool (in the Structure Editing category) to modify a normal arginine into 2MR. You would select the NH1 and change it to be trigonal with three bonds (which will add two hydrogens), then select a hydrogen and change it to be a tetrahedral carbon named CQ1 with 4 bonds (i.e. a methyl group). Do a similar sequence with the NH2. Before you make any changes, ensure that the "Residue Name" section of the tool is set to "Change modified residue's name to 2MR". --Eric Eric Pettersen UCSF Computer Graphics Lab

Hi,
In ChimeraX can a regular residue be replaced with an unusual one using the swapaa function(pdb code 2MR)?
