User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a L-histidine derivative and a non-proteinogenic L-alpha-amino acid. It has a role as a Saccharomyces cerevisiae metabolite. It is a tautomer of a 2-(3-amino-3-carboxypropyl)-L-histidine dizwitterion.
Assistant: This is a molecule that fits this description: NC(CCc1ncc(C[C@H](N)C(=O)O)[nH]1)C(=O)O
