User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is an L-alpha-amino acid zwitterion formed from hercynylselenocysteine by transfer of a proton from the carboxy to the amino group; major species at pH 7.3. It is a tautomer of a hercynylselenocysteine.
Assistant: This is a molecule that fits your description: C[N+](C)(C)[C@@H](Cc1cnc([Se]C[C@H]([NH3+])C(=O)[O-])[nH]1)C(=O)[O-]
