[Chimera-users] Four letter residue names

A pdb file deriving from a mmCIF file (with chimerax) and comprising both
nucleotides and proteins, shows the protein residue names with four
characters (i.e., using also column 21), such as ALAM in one subunit, or
GLNm in another subunit.
I read on passing somewhere (and I am unable to trace that back) that
chimera accepts such four character names but was unable to find a
description from chimera help. I also got lost in deciphering the
intricacies of mmCIF files. What is the scope of the column 21 character?
Could that simply be ignored, or deleted, for use with the CHARMM FF?
Thanks for advice
