Re: [ccp4bb] restraints for cis-bonds, ACD cif file

Nathaniel The atom names in the file I sent have the correct atom names as defined by the PDB for ACD. Naturally, the atom names in your PDB file and the restraints CIF file should match and given that you need the correct names to deposit your structure into the PDB, then I would recommend doing

I appreciate the input Paul and Nigel. The cif dictionary file you sent me doesn't have matching restraint definitions for 53 atoms in the ACD file. I opened the cif file you sent and extracted the SMILES code for ACD. Then I ran it in phenix.elbow to have it generate a pdb of the ACD. Then i wo

Nathaniel I made a small mod to eLBOW (which will be available in the next nightly build) that allows you to get an all cis ACD from a SMILES string. I have attached the result. Note that the name of the file has for the four cis (zusammen) configurations. As Paul suggested, the torsion value
