Rune You are correct that the ligand RP5 is in the Chemical Components library but the ChemComp is a library of ligand chemical data not ligand geometry restraints. An additional step needs to be performed to convert to restraints for a refinement. The simplest solution is the run ReadySet! on your model. phenix.ready_set model.pdb will generate a new model with hydrogens and ligands with hydrogens and a restraints CIF file for any ligands not in the Monomer library. Contact me again if you still have difficulty. Nigel On 8/12/09 5:11 AM, Rune wederkinck Andersen wrote:
Hi everyone I'm running a refinement in phenix.refine. I'm now trying to ad two subtrates AMP and RP5. The phenix.refine seams to reconise AMP but not the RP5 molecules. It seams as if this molecules is well known for the program (phenix-1.4-3/ext_ref_files/chemical_components/r/data_RP5.cif). In my PDB file the two molecules are described like this: ...

I have tried with phenix.elbow as well but didn't work...
Please help...
