User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is the zwitterion from the dipeptide glycylglycine formed by proton transfer from the OH of the carboxy group to the terminal amino group. It has a role as a human metabolite. It is a tautomer of a glycylglycine.
Assistant: This is a molecule that fits this description: [NH3+]CC(=O)NCC(=O)[O-]
