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: ...
