User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a peptide zwitterion obtained by transfer of a proton from the carboxy to the amino terminus of Gly-Met. It is a tautomer of a Gly-Met.
Assistant: This is a molecule that fits this description: CSCC[C@H](NC(=O)C[NH3+])C(=O)[O-]
