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 1-methylhistidine; major species at pH 7.3. It has a role as a human urinary metabolite. It is a tautomer of a 1-methylhistidine.
Assistant: This is a molecule that fits this description: Cn1cnc(CC([NH3+])C(=O)[O-])c1
