User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is an amino acid zwitterion resulting from the transfer of a proton from the carboxy group to the amino group of 4-(methylamino)butyric acid. It is a tautomer of a 4-(methylamino)butyric acid.
Assistant: This is a molecule that fits your description: C[NH2+]CCCC(=O)[O-]
