User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is an L-alpha-amino acid zwitterion formed from ovothiol C by transfer of a proton from the carboxy to the amino group; major species at pH 7.3. It derives from a L-histidine zwitterion. It is a tautomer of an ovothiol C.
Assistant: This is a molecule that fits this description: Cn1cnc(S)c1C[C@@H](C(=O)[O-])[NH+](C)C
