Hi Daniel, Chimera learns that non-standard residues are modified forms of regular amino/nucleic acids from the MODRES records in PDB files. If you added MODRES records for your residues to your input file, the sequence would show S/T instead of X. The format for a MODRES record is documented here: http://www.wwpdb.org/documentation/file-format-content/format33/sect3.html#M... <http://www.wwpdb.org/documentation/file-format-content/format33/sect3.html#MODRES> You could crib MODRES records for your residues from 1vrv (SEP) and 6ar2 (TPO). You would have to edit the chain ID and sequence number fields of those records. —Eric Eric Pettersen UCSF Computer Graphics Lab

Hi,
I modeled two phosphorylated residues in my structure. The primary sequence window in Chimera, however, is only showing a “X” at those positions. Is there a possibility to change that to the original amino acid (S or T) or to show them as SEP or TPO in the sequence window? Thanks, Daniel
