User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a doubly-charged tricarboxylic acid anion arising from deprotonation of the carboxy groups and protonation of the amino group of 3-epi-3-hydroxymugineic acid. It is a conjugate base of a 3-epi-3-hydroxymugineic acid.
Assistant: This is a molecule that fits this description: O=C([O-])[C@@H]([NH2+]CC[C@H](O)C(=O)[O-])[C@@H](O)CN1C[C@H](O)[C@H]1C(=O)[O-]
