Dear all, I would like to ask for some advice on the best way to handle poorly defined side chains for deposition of a low-resolution (~3.6 Å) X-ray structure.
For a number of residues in my structure, there is little or no side-chain density, so I do not feel confident modelling the full side chains. At the moment, I have deleted the residues that are not supported by the electron density, which also gives better geometry and refinement statistics. I asked the PDBe deposition team whether they had any preference between deleting the unsupported side-chain atoms or keeping them with zero occupancy. They replied that they do not have any specific requirements, as long as the deposited model is appropriate. I was therefore wondering how people here would normally deal with this situation for PDB deposition. Would you generally: * delete the unsupported side-chain atoms, * keep the full side chains but set the unsupported atoms to zero occupancy, * or use another approach? I’d be interested to hear what people usually do for structures around this resolution. Many thanks in advance.
