User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is an optically active form of 4-hydroxyproline having L-trans-configuration. It has a role as a human metabolite, a plant metabolite and a mouse metabolite. It is a tautomer of a trans-4-hydroxy-L-proline zwitterion.
Assistant: This is a molecule that fits your description: O=C(O)[C@@H]1C[C@@H](O)CN1
