RestraintLib API

Programs can use RestraintLib's API to calculate restraints programmatically without interacting with this web page. To see the format of the requests, check the API documentation.

Help

The server generates external scripts with bond length and angle restraints for DNA and RNA oligonucleotides, for the phosphodiester (C-O-PO2-O-C) and monoester (C-O-PO3) groups, nitrogenous bases: adenine, guanine, thymine, uracil, cytosine, isocytosine, isoguanine, and ribose or 2’-deoxyribose sugar rings submitted as PDB files. The output restraint file is compatible with Refmac5, SHELXL and phenix.refine.

Please, upload a PDB file.

You may also want to standardize the placement of your macromolecule in the unit cell using ACHESYM

Privacy

All submitted data will be deleted after 96 hours. Each submission gets a unique, random identification number. Accessing the results is only possible with the identification number.
