User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a zwitterionic form of L-lombricine where the carboxy and phosphate groups are anionic and the amino and guanidino groups are cationic; major species at pH 7.3. It is a tautomer of a L-lombricine.
Assistant: This is a molecule that fits your description: NC(N)=[NH+]CCOP(=O)([O-])OC[C@H]([NH3+])C(=O)[O-]

NC(N)=[NH+]CCOP(=O)([O-])OC[C@H]([NH3+])C(=O)[O-]
C(COP(=O)([O-])OC[C@@H](C(=O)[O-])[NH3+])[NH+]=C(N)N
