User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a tripeptide zwitterion resulting from the transfer of a proton from the carboxy group to the amino group of Gly-Gly-Pro. Major microspecies at pH 7.3. It is a tautomer of a Gly-Gly-Pro.
Assistant: This is a molecule that fits your description: [NH3+]CC(=O)NCC(=O)N1CCC[C@H]1C(=O)[O-]
