User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is an L-alpha-amino acid zwitterion that results from the transfer of a proton from the carboxylic acid group to the alpha-amino group of N(3)-fumaramoyl-(S)-2,3-diaminopropanoic acid; major species at pH 7.3. It is a tautomer of a N(3)-fumaramoyl-(S)-2,3-diaminopropanoic acid.
Assistant: This is a molecule that fits your description: NC(=O)/C=C/C(=O)NC[C@H]([NH3+])C(=O)[O-]
