User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a 2-(3-amino-3-carboxypropyl)-L-histidine in which position 3 on the side-chain has S-configuration. It is a tautomer of a 2-[(3S)-3-amino-3-carboxypropyl]-L-histidine dizwitterion.
Assistant: This is a molecule that fits this description: N[C@@H](CCc1ncc(C[C@H](N)C(=O)O)[nH]1)C(=O)O
