Try the program disulfide by design: http://www.ehscenter.org/dbd/ Its easy to install (at least on windows) and to run. You put in a PDB file and the program will look in the structure where disulphide bonds are possible. It also ranks the candidates in energies. Finally, it can generate a PDB file with a particular disulphide. Quite a nice program.

I intend to mutate a couple of residues to cysteines(so that they form a disulphide linkage) in a certain region of my protein. Could I please be directed to program(s) that would reliably let me do that, prior to primer designing? Thanks in advance, Amit
