User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a C4-dicarboxylate that is the E-isomer of but-2-enedioate(2-) It has a role as a metabolite, a human metabolite and a Saccharomyces cerevisiae metabolite. It is a butenedioate and a C4-dicarboxylate. It is a conjugate base of a fumarate(1-).
Assistant: This is a molecule that fits your description: O=C([O-])/C=C/C(=O)[O-]
