Ah...good point: if your modified amino acid is not in the components.cif
file provided by the RCSB, you'll have to proceed by a different method:
Create a pdb file with all hydrogens for your residue plus capping residues,
convert that to .ac format with antechamber, and proceed as in the tutorial.
In practice, the R.E.D. tools may be better set up to do this sort of thing
(not sure, since I haven't had time to learn R.E.D. myself.
...good luck...dac
Note: if you want to check the components.cif file to see if your modification
is one that is present in the PDB, you can download the "Chemical Components
Library" from
http://rcsb.org: look under the "Deposit" Menu item.
