User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a peptide anion that is the conjugate base of pyroglutamylglutamine, obtained by deprotonation of the carboxy group; major species at pH 7.3. It has a role as a human metabolite. It is a conjugate base of a pyroglutamylglutamine.
Assistant: This is a molecule that fits this description: NC(=O)CC[C@H](NC(=O)[C@@H]1CCC(=O)N1)C(=O)[O-]
