Hi Andrew,
You can do a virtual mutation, i.e. change one amino acid type to another, with the “swapaa” command.  Although it will try to use a reasonable conformation of the new sidechain, it will not predict how any other parts of the structure might change.  The other parts of the structure will stay exactly the same.

See the “swapaa” manual page for command options and several examples:

I hope this helps,
