Task: Please create a SMILES based on the text description below.
Description: The molecule is an amino acid zwitterion resulting from a transfer of a proton from the carboxy to the amino group of 4-oxo-L-proline; major species at pH 7.3. It is a tautomer of a 4-oxo-L-proline.
Result: O=C1C[NH2+][C@H](C(=O)[O-])C1
