User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is a peptide zwitterion obtained by transfer of a proton from the carboxy to the amino terminus of Phe-Ala; major species at pH 7.3. It is a tautomer of a Phe-Ala.
Assistant: This is a molecule that fits this description: C[C@H](NC(=O)[C@@H]([NH3+])Cc1ccccc1)C(=O)[O-]
