User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is an L-alpha-amino acid zwitterion obtained by transfer of a proton from the carboxy to the amino group of N-methylproline; major species at pH 7.3. It has a role as a plant metabolite and a human metabolite. It is a tautomer of a N-methylproline.
Assistant: This is a molecule that fits your description: C[NH+]1CCC[C@H]1C(=O)[O-]
