User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a dicarboxylic acid dianion obtained by deprotonation of the carboxy groups of (3E)-phycocyanobilin; major species at pH 7.3. It is a dicarboxylic acid dianion and a linear tetrapyrrole anion. It is a conjugate base of a (3E)-phycocyanobilin.
Assistant: This is a molecule that fits your description: C/C=C1C(=C/c2[nH]c(/C=c3\[nH]/c(=C\C4=NC(=O)C(CC)=C4C)c(C)c3CCC(=O)[O-])c(CCC(=O)[O-])c2C)/NC(=O)[C@@H]/1C
