User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a tricarboxylic acid dianion obtained by deprotonation of the three carboxy groups and protonation of the secondary amino group of N-[(2S)-2-amino-2-carboxyethyl]-L-glutamic acid. It is the major microspecies at pH 7.3 (according to Marvin v 6.2.0.). It is a conjugate base of a N-[(2S)-2-amino-2-carboxyethyl]-L-glutamic acid.
Assistant: This is a molecule that fits this description: N[C@@H](C[NH2+][C@@H](CCC(=O)[O-])C(=O)[O-])C(=O)[O-]
