Task: Please generate a molecule SMILES based on the description below.
Description: The molecule is a dipeptide zwitterion obtained by transfer of two protons from the carboxy to the amino and guanidino groups of beta-Asp-Arg; major species at pH 7.3. It is a tautomer of a beta-Asp-Arg.
Result: NC(N)=[NH+]CCC[C@H](NC(=O)C[C@H]([NH3+])C(=O)[O-])C(=O)[O-]
