On this page you can see 3D representation of the protein chain you choose and its basic annotation.
You also can see its primary and secondary structure.
Please select a single amino acid residue you would like to substitute. When you select one, system will present you a list of available substitutions to be applied. Please select one and press "Run calculation" button.
Site will enqueue your task to be calculated and then you'll get the report. Example of a report can be found here.
Warning:
not every structure can be correctly modified. Some structures in PDB
database are not correct enough. Unfortunately, there is no way to
predict such problems before calculation is started, so there is always a
risk to get an error because of bad structure.
