User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is allantoic acid in which one of the aminocarbonyl groups is replaced by hydrogen. It is a member of ureas and a non-proteinogenic alpha-amino acid. It is a tautomer of a 2-ureidoglycine zwitterion.
Assistant: This is a molecule that fits this description: NC(=O)NC(N)C(=O)O
