User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a zwitterion obtained by transfer of a proton from the carboxy to the guanidino group of 5-guanidino-3-methyl-2-oxopentanoic acid; major species at pH 7.3. It is a tautomer of a 5-guanidino-3-methyl-2-oxopentanoic acid.
Assistant: This is a molecule that fits your description: CC(CC[NH+]=C(N)N)C(=O)C(=O)[O-]
