User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is an amino acid zwitterion arising from transfer of a proton from the carboxy to the amino group of L-allysine; major species at pH 7.3. It is a tautomer of a L-allysine.
Assistant: This is a molecule that fits your description: [NH3+][C@@H](CCCC=O)C(=O)[O-]
