Dear Lu,
You could do this in Coot as well if you are uncomfortable doing this in a text editor. First change the residue numbers so they do not overlap, then change the chainID.
Rather than putting all your sulfates in a separate chain, it is better to add them to the correct protein chain. PDB annotation will do this upon deposition otherwise. You should also give NCS-related sulfates (if you have any), the same residue number. It makes it easier to deal with them in the future.
Cheers,
Robbie
