Hi Dhiraj - In addition to the other good suggestions, you may also wish to try codon optimization and different secretion signal peptides if your target protein is secreted. Hope that helps. Cheers, Jared On Thu, Jun 24, 2021 at 4:42 PM Srivastava, Dhiraj < dhiraj-srivast...@uiowa.edu> wrote:

That's right. The S-OH configuration is imposed by the CIF dictionary for the ligand that you are using in REFMAC. You can edit the dictionary with e.g., jligand, save a local copy and feed that copy to REFMAC - it will override the library definition of the ligand. On 25/06/2021 10:58, Pea

Hello Shipra, If you have defined the small molecule with a cif dictionary file (used for refinement in REFMAC), then take a look at that file and see whether it is correctly defined. You can manually edit these files or remake them using any number of programs to get the parameters you think a

[ccp4bb] S=O converted to S-OH during refinement

2021-06-25 Thread Shipra Bijpuria
Hello everyone, I am trying to refine a protein-ligand complex structure. The ligand is a small molecule and at one end has Sulfur that has three branches of O, NH and CH3. Sulfur is attached to oxygen by a double bond (S=O). After fitting the ligand, I did refinement using Refmac5 with default s
