User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is an alpha-amino-acid anion that is the conjugate base of O-succinyl-L-homoserine having anionic carboxy groups and a protonated amino group; major species at pH 7.3. It has a role as an Escherichia coli metabolite and a Saccharomyces cerevisiae metabolite. It is a dicarboxylic acid anion and an alpha-amino-acid anion. It is a conjugate base of an O-succinyl-L-homoserine.
Assistant: This is a molecule that fits your description: [NH3+][C@@H](CCOC(=O)CCC(=O)[O-])C(=O)[O-]
