Hi Jackie, If the PDB file has a MODRES record that specifies the "normal" form of the residue, then I believe it will show up as K when you display the sequence. For example, if I use these commands open 7k3m select :kcx ...and then show its sequence (menu: Favorites... Sequence) I can see that the selected residue is "K" in the sequence. The PDB file for 7k3m contains this MODRES line: MODRES 7K3M KCX A 71 LYS MODIFIED RESIDUE I hope this helps, Elaine ----- Elaine C.

I have a "residue" KCX (PDB records are Hetatm). In the sequence alignment it comes as X. Is there a way to change it to K without making a PDB file and changing it to K there? Thank you,.
