User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is a hydrogen butenedioate obtained by deprotonation of one of the carboxy groups of fumaric acid. It has a role as a fundamental metabolite. It is a conjugate base of a fumaric acid. It is a conjugate acid of a fumarate(2-).
Assistant: This is a molecule that fits this description: O=C([O-])/C=C/C(=O)O
