User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is an amino acid zwitterion arising from transfer of a proton from the carboxy to the amino group of 4-hydroxy-L-threonine; major species at pH 7.3. It is a tautomer of a 4-hydroxy-L-threonine.
Assistant: This is a molecule that fits this description: [NH3+][C@H](C(=O)[O-])[C@H](O)CO
