If I understand you correctly, you want to create
N(epsilon)-Acetyl-L-lysine residues, right? If that is the case, then
the ACE patch is not readily applicable as it is: you can build your
own patch using ACE as a template, but you need to modify it in order
to delete two of the hydrogens atoms of the -NH3+ group of lysine and
then make a bond between the NZ atom and the acetyl group.
