User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is an amino acid zwitterion obtained from N(2)-(2-carboxyethyl)-L-arginine by the removal of a proton for both of the carboxy groups and the addition of a proton to the alpha-amino group and to the guanidyl group. It is a tautomer of a N(2)-(2-carboxyethyl)-L-arginine.
Assistant: This is a molecule that fits your description: NC(N)=[NH+]CCC[C@H]([NH2+]CCC(=O)[O-])C(=O)[O-]
