Generate and visualize the symmetry equivalent macromolecules (proteins and nucleic acids).
Highlights:
SEM is a web-based graphical user interface to generate and visualize the symmetry equivalent molecules (proteins and nucleic acids).
In addition, the program allows the users to save the three-dimensional atomic coordinates of the symmetry equivalent molecules in the local machine.
The graphics program RasMol has been deployed to visualize the reference (input atomic coordinates) and the symmetry equivalent molecules.
This program is written using CGI/Perl scripts and has been interfaced with all the three-dimensional structures (solved using X-ray crystallography) available in the Protein Data Bank.
