Task: Please create a text description for a molecule based on its representation.
Molecule SMILES: C[S+](CCC(=O)C(=O)[O-])C[C@H]1O[C@@H](n2cnc3c(N)ncnc32)[C@H](O)[C@@H]1O
Constraint: Answer the question with full sentences.
Result: The molecule is a sulfonium betaine that is the conjugate base of S-adenosyl-4-methylthio-2-oxobutanoic acid, arising from deprotonation of the carboxy group. It has a role as a Saccharomyces cerevisiae metabolite. It is a sulfonium betaine and a carboxylic acid anion. It derives from a 4-methylthio-2-oxobutanoate. It is a conjugate base of a S-adenosyl-4-methylthio-2-oxobutanoic acid.
