<div dir="ltr">Xavier<div><br></div><div>Paul's point is very valid because the "Prepare for Deposition" step is what generates the sequence (which is the crucial point here) for deposition. However, because you have "created" a new amino acid, there will still be issues as highlighted by Pavel. It is a corner case. </div><div><br></div><div>One small addition point is that SLG is already taken in the PDB Ligand list. There are tools in Phenix to find an used code.</div><div><br></div><div>Can you re-engineer it with SER+ligand? This will solve the problem using the current Phenix version.

For this I’ve generated the molecules in SMILES and used eLBOW to generate the restraints.
