User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is an amino acid zwitterion arising from transfer of a proton from the carboxy to the amino group cis-4-hydroxy-L-proline; major species at pH 7.3. It is a tautomer of a cis-4-hydroxy-L-proline.
Assistant: This is a molecule that fits your description: O=C([O-])[C@@H]1C[C@H](O)C[NH2+]1
