User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is a tetracarboxylic acid anion resulting from the protonation of the amino group and the deprotonation of all four carboxy groups of fumonisin B1. This is the major species at pH 7.3. It is an ammonium ion derivative and a tetracarboxylic acid anion. It is a conjugate base of a fumonisin B1.
