User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a cysteine derivative that is L-cysteine in which the hydrogen attached to the sulfur is replaced by a methyl group. It has a role as a human urinary metabolite and a plant metabolite. It is a tautomer of a S-methylcysteine zwitterion.
Assistant: This is a molecule that fits this description: CSC[C@H](N)C(=O)O
