Dear Gustavo,
 
If you look at the following tutorial it details how to use xleap to create
a non-standard residue. In the case of the tutorial a copper bound
histidine. You could easily adapt this for your non-standard amino acid.
 
see:

All the best
Ross

Subject: AMBER: new aminoacid


Hi, I am trying to make leap recognize the pdb input that has a non-
standard aminoacid. I have made the .in file, an have already developed the
parameters. The problems is that when I load the input.pdb the parameters
that are absents are not what they should be. For example, it appears that a
CW-C bond is absent, but I have not this bond in the non standard aminoacid.
The question is the following: should I add other information besides .in
file? I believe that the connection information is wrong, and should add
this new aminoacid to the file all_amino94.lib
Thanks in advance
Gustavo
