Greetings, everyone. I got the pdb file of an enzyme, but I don’t know how to write the constraints of its active sites.
Could anyone help me solve this problem?
Much appreciate it.When I open the pdb file with txteditor, I can see coordinates as:

Hi Albert !
I use pymol for calculating the distance, angles and dihedrals between the two residues.
To know more about constraints go to https://www.rosettacommons.org/manuals/archive/rosetta3.1_user_guide/file_constraints.html -

Hi Albert,
In addition, if you know python, you can look into using PyRosetta and the iPython shell to do it in code. -

That’s just what I’ve been looking for. Thank you very much!
