User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is a quaternary ammonium ion that is the derivative of L-histidine having a 4-amino-4-oxo-3-(trimethylammonio)butyl group at the 2-position of the imidazole ring. It is a tautomer of a diphthamide zwitterion.
Assistant: This is a molecule that fits this description: C[N+](C)(C)[C@@H](CCc1ncc(C[C@H](N)C(=O)O)[nH]1)C(N)=O
