User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is a dipeptide zwitterion obtained by transfer of a proton from the carboxy to the amino terminus of His-Leu. Major species at pH 7.3. It is a tautomer of a His-Leu.
Assistant: This is a molecule that fits your description: CC(C)C[C@H](NC(=O)[C@@H]([NH3+])Cc1cnc[nH]1)C(=O)[O-]
