User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is an alpha-amino acid zwitterion obtained by transfer of a proton from the carboxy to the amino group of thioproline; major species at pH 7.3. It has a role as an antidote and an antioxidant. It is a tautomer of a thioproline.
Assistant: This is a molecule that fits your description: O=C([O-])C1CSC[NH2+]1
