Task: Please give me a SMILES based on the description below.
Description: The molecule is the 2-oxo monocarboxylic acid anion derived from 4-methylthio-2-oxobutanoic acid. The major microspecies at pH 7.3, it is formed from L-methionine via the action of methionine transaminase. It has a role as a human metabolite and a Saccharomyces cerevisiae metabolite. It derives from a butyrate. It is a conjugate base of a 4-methylthio-2-oxobutanoic acid.
Result: CSCCC(=O)C(=O)[O-]
