User: I want to come up with a SMILES.
Assistant: This sounds very exciting. Should it be a special one?
User: Yes, the molecule can be described by:
The molecule is a dicarboxylic acid dianion obtained by deprotonation of the carboxy groups of (3E)-phycoerythrobilin; 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)-phycoerythrobilin.
Assistant: Ok, this SMILES fits your description: C=CC1=C(C)[C@@H](Cc2[nH]c(/C=c3\[nH]/c(=C\C4=NC(=O)[C@H](C)/C4=C\C)c(C)c3CCC(=O)[O-])c(CCC(=O)[O-])c2C)NC1=O
