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