Hi Pascal, phenix.refine does not write any LINK records to PDB file with refined model or any similar geometry restraints information. All this information (all the information about geometry restraints used in refinement) is stored in .geo file. Pavel. On 2/23/09 11:33 AM, Pascal Egea wrote:

Dear All,

I apologize if this question has already been answered. I am refining a structure of a glycosylated-enzyme and I understood the way to define all the links (N-glycosylation to the ASN and beta-glycosidic bonds between the NAG units) and refinement is complete and everything is good. All the links I included in my cif_link definition file where taken into account and dealt with by Phenix (the .def and .geo files are fine). Is it normal however that in the resulting refined PDB file, no such links are written by PHENIX under the REMARK 3 record ? Same thing for the 5 disulfide bonds present in the protein.

Thanks in advance for the clarification.
