User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is an L-methionine derivative in which the sulfur has been oxidised to the corresponding sulfone. It has a role as an animal metabolite. It is a L-methionine derivative, a non-proteinogenic L-alpha-amino acid and a methionine sulfone. It is a tautomer of a methionine sulfone zwitterion.
Assistant: This is a molecule that fits this description: CS(=O)(=O)CC[C@H](N)C(=O)O
