User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is a tetracarboxylic acid anion obtained by deprotonation of the four carboxy groups of beta-citrylglutamic acid; major species at pH 7.3. It is a tetracarboxylic acid anion and a N-acyl-L-alpha-amino acid anion.
Assistant: This is a molecule that fits your description: O=C([O-])CC[C@H](NC(=O)C(O)(CC(=O)[O-])CC(=O)[O-])C(=O)[O-]
