User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a dipeptide zwitterion obtained by transfer of a proton from the carboxy to the amino terminus of Pro-Ala. Major species at pH 7.3. It has a role as a metabolite. It is a tautomer of a Pro-Ala.
Assistant: This is a molecule that fits this description: C[C@H](NC(=O)[C@@H]1CCC[NH2+]1)C(=O)[O-]
