User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is an optically active form of malate having (R)-configuration. It is a conjugate base of a (R)-malic acid. It is an enantiomer of a (S)-malate(2-).
Assistant: This is a molecule that fits this description: O=C([O-])C[C@@H](O)C(=O)[O-]
