User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a tetrapeptide composed of L-lysine and three L-methionine units joined in sequence by peptide linkages. It has a role as a metabolite. It derives from a L-lysine and a L-methionine.
Assistant: This is a molecule that fits your description: CSCC[C@H](NC(=O)[C@H](CCSC)NC(=O)[C@H](CCSC)NC(=O)[C@@H](N)CCCCN)C(=O)O
