User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a D-alpha-amino acid zwitterion that is D-proline in which a proton has been transferred from the carboxy group to the amino group. It is the major species at pH 7.3. It is a tautomer of a D-proline.
Assistant: This is a molecule that fits your description: O=C([O-])[C@H]1CCC[NH2+]1
