User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a D-alpha-amino acid zwitterion that is D-allothreonine in which a proton has been transferred from the carboxy group to the amino group. It is the major species at pH 7.3. It is a tautomer of a D-allothreonine.
Assistant: This is a molecule that fits your description: C[C@@H](O)[C@@H]([NH3+])C(=O)[O-]
