User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a peptide anion that is the conjugate base of L-alanyl-D-glutamic acid, arising from deprotonation of the the two carboxy groups and protonation of the amino group; major species at pH 7.3.
Assistant: This is a molecule that fits this description: C[C@H]([NH3+])C(=O)N[C@H](CCC(=O)[O-])C(=O)[O-]
