“resname” selects atoms based on their assigned residue names.

resname residue-name-pattern
resn residue-name-pattern
r. residue-name-pattern

indicate resname his
color blue, resn arg+lys+his
indicate r. gl*
select acids, resn asp+glu

PyMOL supports residue names of up to four characters. However, the PDB file format cannot accomodate these names.

The strict macro equivalent is residue-name-pattern`/, however the back apostrophe can be omitted in most cases to allow for residue-name-pattern/.

indicate phe`/
indicate phe/
indicate arg+his+lys/
