User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a monocarboxylic acid anion that is the conjugate base of allantoic acid. It has a role as a human metabolite and a Saccharomyces cerevisiae metabolite. It is a member of ureas and a monocarboxylic acid anion. It is a conjugate base of an allantoic acid.
Assistant: This is a molecule that fits this description: NC(=O)NC(NC(N)=O)C(=O)[O-]
