User: I want to come up with a SMILES.
Assistant: This sounds very exciting. Should it be a special one?
User: Yes, the molecule can be described as:
The molecule is an alpha-amino-acid cation obtained by protonation of the imidazole ring of ergothioneine. It is the major microspecies at pH 7.3 (according to Marvin v 6.2.0.). It is a conjugate acid of an ergothioneine.
Assistant: Ok, this SMILES fits your description: C[N+](C)(C)[C@@H](Cc1c[nH+]c(S)[nH]1)C(=O)[O-]
