Task: Please give me a molecule SMILES based on the description below.
Description: The molecule is a dizwitterionic form of 2-(3-amino-3-carboxypropyl)-L-histidine arising from transfer of two protons from the carboxy to the amino groups; major species at pH 7.3. It is a tautomer of a 2-(3-amino-3-carboxypropyl)-L-histidine.
Result: [NH3+]C(CCc1ncc(C[C@H]([NH3+])C(=O)[O-])[nH]1)C(=O)[O-]
