Identification
Name:2-Maleylacetate
Description2-maleylacetate belongs to the class of Medium-chain Keto Acids and Derivatives. These are keto acids with a 6 to 12 carbon atoms long side chain. (inferred from compound structure)<br/><br/>2-Maleylacetate is involved in the degradation pathway of aromatic compounds. Reduction of the double bond in maleylacetate is catalyzed by the enzyme maleylacetate reductase, which was also purified from E. coli (PMID 8900023)
