User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a tetrapeptide composed of L-proline, L-valine, glycine, and L-proline joined by peptide linkages. It has a role as a metabolite. It derives from a L-proline, a L-valine and a glycine.
Assistant: This is a molecule that fits this description: CC(C)[C@H](NC(=O)[C@@H]1CCCN1)C(=O)NCC(=O)N1CCC[C@H]1C(=O)O
