User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is an amino acid zwitterion obtained by transfer of a proton from the carboxy to the amino group of N(2)-acetyl-L-lysine; major species at pH 7.3. It has a role as a human metabolite. It is a tautomer of a N(2)-acetyl-L-lysine.
Assistant: This is a molecule that fits your description: CC(=O)N[C@@H](CCCC[NH3+])C(=O)[O-]
