Leap will only recognize residues that it is told about in library files.
When you source leaprc.ff___, it loads OFF libraries that contain the names
of all common residues (and their structures and attributes). Thus, if your
substrate residue is not one of the common amino acids (or nucleic acids),
you will likely need to create your own 'custom' residue. There are
tutorials that will walk you through this process on the amber tutorial
webpage here: http://ambermd.org/tutorials/ . Tutorials B4 and A1 and
A1.old will likely provide all the help you'll need to do this.
Good luck!
