User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is an L-alpha-amino acid zwitterion formed from ovothiol B 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 B.
Assistant: This is a molecule that fits this description: C[NH2+][C@@H](Cc1c(S)ncn1C)C(=O)[O-]
