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 cis-3-hydroxy-D-proline; major species at pH 7.3 It is a tautomer of a cis-3-hydroxy-D-proline.
Assistant: This is a molecule that fits this description: O=C([O-])[C@@H]1[NH2+]CC[C@@H]1O
